Addresses #1135, some code cleanup and refactoring. Changes wrapper function which handles testing, further modularized code, added test to cover function call fixing, and fixed duplicate test function name.
New commit supports the above import format, however it does not fix function calls elsewhere in the source. Perhaps there should be an error or simply alert the user through stdout().
Moved away from using manual parsing. Source is parsed using RedBaron to make the FST. Some import formats not yet implemented, and still some bugs to work out. However, the current script works well for the two cases in the file comments.
