 Changelog
 ---------
 
+2012-08-21: Made storage tank participate in autoplace algorithm.  Tuned API a 
+little to allow for more flexible placement.
+
+2012-08-20: Added temporary nodes for storage tank and intake grating, but 
+without autoplace.
+
 2012-08-19: Pumps and valves now fully participate in the 
 auto-rotate/auto-place algorithm.
