Adding detailed comments to all modules to improve maintainability and make it easier for new contributors
Some improvements in commenting standards can be
Comment on each file which mentions last modification date & commit (should be automated)
Better description on top of each file
Stores should mention on which views are they being used, etc
For our 'license', suggest that we just have a 1-liner saying that ~"This code is subject to the Raxa license; as of October 4th, 2012 this license was Apache 2.0. For more details, visit: <url>". That way it won't take up so much space in every file...
