"""
Tool for automagically updating the paths in visual studio project files.
Is part of the git commit hook, or can be just ran manually.
Takes no arguments, the paths are hardcoded here.
Tested to work with both python 2.7.9 and 3.4.3

(Python's default XML libraries are so horrible this just parses files as lines)
