packaged for distutils

I've setup the Mcl Github's fork with a distutils package.

A couple of notes:

1. In the LICENSE I've made the Copyright 2013 Elizabeth McNany (Hopefully this name is correct, let me know if I got it really wrong and I'll change it). 
2. In the code, I've made the Copyright 2013 UMD Metacognitive Lab

I'll let you choose what you want to do- just let me know. 

Also, I've made the license GPLv2 because that is what the Berkeley Parser's license is. 

Anyway, let me know what you think.
