* closes #25 - move layer folders inside project package and update
quickstart
* closes #95 - update documentation for v0.3

v0.3.1

Caramel Corn CONSTANTS

Caramel Corn Catastrophe

Fix issue with release robot, in distribution, usage fails because package in python27\lib\site-packages or /usr/lib/python2.7/site-packages is not a Git repositiory. Solution is similar to versioneer, write VERSION to a module called version.py, try to import it and compare it to the dulwich version. If not a match, update the file with the latest tag.
