+GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+
+THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE
+COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
+COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS
+AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.
+
+BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE
+TO BE BOUND BY THE TERMS OF THIS LICENSE. TO THE EXTENT THIS LICENSE MAY
+BE CONSIDERED TO BE A CONTRACT, THE LICENSOR GRANTS YOU THE RIGHTS
+CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND
+CONDITIONS.
+
+1. Definitions
+
+ a. "Adaptation" means a work based upon the Work, or upon the Work and
+    other pre-existing works, such as a translation, adaptation,
+    derivative work, arrangement of music or other alterations of a
+    literary or artistic work, or phonogram or performance and includes
+    cinematographic adaptations or any other form in which the Work may be
+    recast, transformed, or adapted including in any form recognizably
+    derived from the original, except that a work that constitutes a
+    Collection will not be considered an Adaptation for the purpose of
+    this License. For the avoidance of doubt, where the Work is a musical
+    work, performance or phonogram, the synchronization of the Work in
+    timed-relation with a moving image ("synching") will be considered an
+    Adaptation for the purpose of this License.
+ b. "Collection" means a collection of literary or artistic works, such as
+    encyclopedias and anthologies, or performances, phonograms or
+    broadcasts, or other works or subject matter other than works listed
+    in Section 1(f) below, which, by reason of the selection and
+    arrangement of their contents, constitute intellectual creations, in
+    which the Work is included in its entirety in unmodified form along
+    with one or more other contributions, each constituting separate and
+    independent works in themselves, which together are assembled into a
+    collective whole. A work that constitutes a Collection will not be
+    considered an Adaptation (as defined below) for the purposes of this
+    License.
+ c. "Creative Commons Compatible License" means a license that is listed
+    at http://creativecommons.org/compatiblelicenses that has been
+    approved by Creative Commons as being essentially equivalent to this
+    License, including, at a minimum, because that license: (i) contains
+    terms that have the same purpose, meaning and effect as the License
+    Elements of this License; and, (ii) explicitly permits the relicensing
+    of adaptations of works made available under that license under this
+    License or a Creative Commons jurisdiction license with the same
+    License Elements as this License.
+ d. "Distribute" means to make available to the public the original and
+    copies of the Work or Adaptation, as appropriate, through sale or

+    musicians, dancers, and other persons who act, sing, deliver, declaim,
+    play in, interpret or otherwise perform literary or artistic works or
+    expressions of folklore; (ii) in the case of a phonogram the producer
+    being the person or legal entity who first fixes the sounds of a
+    performance or other sounds; and, (iii) in the case of broadcasts, the
+    organization that transmits the broadcast.
+ h. "Work" means the literary and/or artistic work offered under the terms
+    of this License including without limitation any production in the
+    literary, scientific and artistic domain, whatever may be the mode or
+    form of its expression including digital form, such as a book,
+    pamphlet and other writing; a lecture, address, sermon or other work
+    of the same nature; a dramatic or dramatico-musical work; a
+    choreographic work or entertainment in dumb show; a musical
+    composition with or without words; a cinematographic work to which are
+    assimilated works expressed by a process analogous to cinematography;
+    a work of drawing, painting, architecture, sculpture, engraving or
+    lithography; a photographic work to which are assimilated works
+    expressed by a process analogous to photography; a work of applied
+    art; an illustration, map, plan, sketch or three-dimensional work

+    extent it is protected as a copyrightable work; or a work performed by
+    a variety or circus performer to the extent it is not otherwise
+    considered a literary or artistic work.
+ i. "You" means an individual or entity exercising rights under this
+    License who has not previously violated the terms of this License with
+    respect to the Work, or who has received express permission from the
+    Licensor to exercise rights under this License despite a previous
+    violation.
+ j. "Publicly Perform" means to perform public recitations of the Work and
+    to communicate to the public those public recitations, by any means or
+    process, including by wire or wireless means or public digital

+    members of the public may access these Works from a place and at a
+    place individually chosen by them; to perform the Work to the public
+    by any means or process and the communication to the public of the

+    medium.
+
+2. Fair Dealing Rights. Nothing in this License is intended to reduce,
+limit, or restrict any uses free from copyright or rights arising from
+limitations or exceptions that are provided for in connection with the
+copyright protection under copyright law or other applicable laws.
+
+3. License Grant. Subject to the terms and conditions of this License,
+Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
+perpetual (for the duration of the applicable copyright) license to
+exercise the rights in the Work as stated below:
+
+ a. to Reproduce the Work, to incorporate the Work into one or more
+    Collections, and to Reproduce the Work as incorporated in the
+    Collections;
+ b. to create and Reproduce Adaptations provided that any such Adaptation,
+    including any translation in any medium, takes reasonable steps to
+    clearly label, demarcate or otherwise identify that changes were made
+    to the original Work. For example, a translation could be marked "The
+    original work was translated from English to Spanish," or a
+    modification could indicate "The original work has been modified.";
+ c. to Distribute and Publicly Perform the Work including as incorporated
+    in Collections; and,
+ d. to Distribute and Publicly Perform Adaptations.
+ e. For the avoidance of doubt:
+
+     i. Non-waivable Compulsory License Schemes. In those jurisdictions in
+        which the right to collect royalties through any statutory or
+        compulsory licensing scheme cannot be waived, the Licensor
+        reserves the exclusive right to collect such royalties for any
+        exercise by You of the rights granted under this License;
+    ii. Waivable Compulsory License Schemes. In those jurisdictions in
+        which the right to collect royalties through any statutory or
+        compulsory licensing scheme can be waived, the Licensor waives the
+        exclusive right to collect such royalties for any exercise by You
+        of the rights granted under this License; and,
+   iii. Voluntary License Schemes. The Licensor waives the right to
+        collect royalties, whether individually or, in the event that the
+        Licensor is a member of a collecting society that administers
+        voluntary licensing schemes, via that society, from any exercise
+        by You of the rights granted under this License.
+
+The above rights may be exercised in all media and formats whether now
+known or hereafter devised. The above rights include the right to make
+such modifications as are technically necessary to exercise the rights in
+other media and formats. Subject to Section 8(f), all rights not expressly
+granted by Licensor are hereby reserved.
+
+4. Restrictions. The license granted in Section 3 above is expressly made
+subject to and limited by the following restrictions:
+
+ a. You may Distribute or Publicly Perform the Work only under the terms
+    of this License. You must include a copy of, or the Uniform Resource
+    Identifier (URI) for, this License with every copy of the Work You
+    Distribute or Publicly Perform. You may not offer or impose any terms
+    on the Work that restrict the terms of this License or the ability of
+    the recipient of the Work to exercise the rights granted to that
+    recipient under the terms of the License. You may not sublicense the
+    Work. You must keep intact all notices that refer to this License and
+    to the disclaimer of warranties with every copy of the Work You
+    Distribute or Publicly Perform. When You Distribute or Publicly
+    Perform the Work, You may not impose any effective technological
+    measures on the Work that restrict the ability of a recipient of the
+    Work from You to exercise the rights granted to that recipient under
+    the terms of the License. This Section 4(a) applies to the Work as
+    incorporated in a Collection, but this does not require the Collection
+    apart from the Work itself to be made subject to the terms of this
+    License. If You create a Collection, upon notice from any Licensor You
+    must, to the extent practicable, remove from the Collection any credit
+    as required by Section 4(c), as requested. If You create an
+    Adaptation, upon notice from any Licensor You must, to the extent
+    practicable, remove from the Adaptation any credit as required by
+    Section 4(c), as requested.
+ b. You may Distribute or Publicly Perform an Adaptation only under the
+    terms of: (i) this License; (ii) a later version of this License with
+    the same License Elements as this License; (iii) a Creative Commons
+    jurisdiction license (either this or a later license version) that
+    contains the same License Elements as this License (e.g.,
+    Attribution-ShareAlike 3.0 US)); (iv) a Creative Commons Compatible
+    License. If you license the Adaptation under one of the licenses
+    mentioned in (iv), you must comply with the terms of that license. If
+    you license the Adaptation under the terms of any of the licenses
+    mentioned in (i), (ii) or (iii) (the "Applicable License"), you must
+    comply with the terms of the Applicable License generally and the
+    following provisions: (I) You must include a copy of, or the URI for,
+    the Applicable License with every copy of each Adaptation You
+    Distribute or Publicly Perform; (II) You may not offer or impose any
+    terms on the Adaptation that restrict the terms of the Applicable
+    License or the ability of the recipient of the Adaptation to exercise
+    the rights granted to that recipient under the terms of the Applicable
+    License; (III) You must keep intact all notices that refer to the
+    Applicable License and to the disclaimer of warranties with every copy
+    of the Work as included in the Adaptation You Distribute or Publicly
+    Perform; (IV) when You Distribute or Publicly Perform the Adaptation,
+    You may not impose any effective technological measures on the
+    Adaptation that restrict the ability of a recipient of the Adaptation
+    from You to exercise the rights granted to that recipient under the
+    terms of the Applicable License. This Section 4(b) applies to the
+    Adaptation as incorporated in a Collection, but this does not require
+    the Collection apart from the Adaptation itself to be made subject to
+    the terms of the Applicable License.
+ c. If You Distribute, or Publicly Perform the Work or any Adaptations or
+    Collections, You must, unless a request has been made pursuant to
+    Section 4(a), keep intact all copyright notices for the Work and
+    provide, reasonable to the medium or means You are utilizing: (i) the
+    name of the Original Author (or pseudonym, if applicable) if supplied,
+    and/or if the Original Author and/or Licensor designate another party
+    or parties (e.g., a sponsor institute, publishing entity, journal) for
+    attribution ("Attribution Parties") in Licensor's copyright notice,
+    terms of service or by other reasonable means, the name of such party
+    or parties; (ii) the title of the Work if supplied; (iii) to the
+    extent reasonably practicable, the URI, if any, that Licensor
+    specifies to be associated with the Work, unless such URI does not
+    refer to the copyright notice or licensing information for the Work;
+    and (iv) , consistent with Ssection 3(b), in the case of an
+    Adaptation, a credit identifying the use of the Work in the Adaptation
+    (e.g., "French translation of the Work by Original Author," or
+    "Screenplay based on original Work by Original Author"). The credit
+    required by this Section 4(c) may be implemented in any reasonable
+    manner; provided, however, that in the case of a Adaptation or
+    Collection, at a minimum such credit will appear, if a credit for all
+    contributing authors of the Adaptation or Collection appears, then as
+    part of these credits and in a manner at least as prominent as the
+    credits for the other contributing authors. For the avoidance of
+    doubt, You may only use the credit required by this Section for the
+    purpose of attribution in the manner set out above and, by exercising
+    Your rights under this License, You may not implicitly or explicitly
+    assert or imply any connection with, sponsorship or endorsement by the
+    Original Author, Licensor and/or Attribution Parties, as appropriate,
+    of You or Your use of the Work, without the separate, express prior
+    written permission of the Original Author, Licensor and/or Attribution
+    Parties.
+ d. Except as otherwise agreed in writing by the Licensor or as may be
+    otherwise permitted by applicable law, if You Reproduce, Distribute or
+    Publicly Perform the Work either by itself or as part of any
+    Adaptations or Collections, You must not distort, mutilate, modify or
+    take other derogatory action in relation to the Work which would be
+    prejudicial to the Original Author's honor or reputation. Licensor
+    agrees that in those jurisdictions (e.g. Japan), in which any exercise
+    of the right granted in Section 3(b) of this License (the right to
+    make Adaptations) would be deemed to be a distortion, mutilation,
+    modification or other derogatory action prejudicial to the Original
+    Author's honor and reputation, the Licensor will waive or not assert,
+    as appropriate, this Section, to the fullest extent permitted by the
+    applicable national law, to enable You to reasonably exercise Your
+    right under Section 3(b) of this License (right to make Adaptations)
+    but not otherwise.
+
+5. Representations, Warranties and Disclaimer
+
+UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
+OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
+KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
+INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
+FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
+LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
+WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION
+OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
+
+6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
+LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR
+ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES
+ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS
+BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+7. Termination
+
+ a. This License and the rights granted hereunder will terminate
+    automatically upon any breach by You of the terms of this License.
+    Individuals or entities who have received Adaptations or Collections
+    from You under this License, however, will not have their licenses
+    terminated provided such individuals or entities remain in full
+    compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
+    survive any termination of this License.
+ b. Subject to the above terms and conditions, the license granted here is
+    perpetual (for the duration of the applicable copyright in the Work).
+    Notwithstanding the above, Licensor reserves the right to release the
+    Work under different license terms or to stop distributing the Work at
+    any time; provided, however that any such election will not serve to
+    withdraw this License (or any other license that has been, or is
+    required to be, granted under the terms of this License), and this
+    License will continue in full force and effect unless terminated as
+    stated above.
+
+8. Miscellaneous
+
+ a. Each time You Distribute or Publicly Perform the Work or a Collection,
+    the Licensor offers to the recipient a license to the Work on the same
+    terms and conditions as the license granted to You under this License.
+ b. Each time You Distribute or Publicly Perform an Adaptation, Licensor
+    offers to the recipient a license to the original Work on the same
+    terms and conditions as the license granted to You under this License.
+ c. If any provision of this License is invalid or unenforceable under
+    applicable law, it shall not affect the validity or enforceability of
+    the remainder of the terms of this License, and without further action
+    by the parties to this agreement, such provision shall be reformed to
+    the minimum extent necessary to make such provision valid and
+    enforceable.
+ d. No term or provision of this License shall be deemed waived and no
+    breach consented to unless such waiver or consent shall be in writing
+    and signed by the party to be charged with such waiver or consent.
+ e. This License constitutes the entire agreement between the parties with
+    respect to the Work licensed here. There are no understandings,
+    agreements or representations with respect to the Work not specified
+    here. Licensor shall not be bound by any additional provisions that
+    may appear in any communication from You. This License may not be
+    modified without the mutual written agreement of the Licensor and You.
+ f. The rights granted under, and the subject matter referenced, in this
+    License were drafted utilizing the terminology of the Berne Convention
+    for the Protection of Literary and Artistic Works (as amended on
+    September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
+    Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996
+    and the Universal Copyright Convention (as revised on July 24, 1971).
+    These rights and subject matter take effect in the relevant
+    jurisdiction in which the License terms are sought to be enforced
+    according to the corresponding provisions of the implementation of
+    those treaty provisions in the applicable national law. If the
+    standard suite of rights granted under applicable copyright law
+    includes additional rights not granted under this License, such
+    additional rights are deemed to be included in the License; this
+    License is not intended to restrict the license of any rights under
+    applicable law.
+

+    Creative Commons is not a party to this License, and makes no warranty

+    Commons has expressly identified itself as the Licensor hereunder, it
