Multi language source code parser.

Outputs:

• directory tree
• function list
• function call list

srcprs can only parse c language for now, but support for any other language can be added easly.

I wrote this just because I got bored ;), so be patient while criticizing. The most important feature is function call list, makes quite easy to understand, see the whole code (with the power of graphviz http://www.graphviz.org)
