Forgot to delete the old README.rst
Reorganised the directory structure.
First attempt at refactoring the old Context class.
Refactored Context to a BaseReader class with a PythonReader subclass to handle converting results from greping python files to a GrepTree.
Fixed formatting error in README
Changed recursive function for printing greptrees + cleanup.
Refactoring GrepTools class.

Moved to it's own file, pass in reader class as a param, tap into reader class's TYPE constant to use in argparse description.
Extracted GrepTools._arg_desc_list() to bullet_list().
