-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.

-    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

-    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

-    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

-    play in, interpret or otherwise perform literary or artistic works or
-    expressions of folklore; (ii) in the case of a phonogram the producer

-    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

-    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

-    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.
