This file is base for pushing to Pypi fixes #64, fixes #65.

Including in this commit is setup.py to establish python packaging. There is more we can do with this. This is not intended to be perfect, but a start. 

This was used to update the PyPi record: https://pypi.python.org/pypi/Mesa/
So, if you want to edit the PyPi record, the preferred way to do this is in the setup.py, then uploading a new dist to PyPi. 

What does this all mean? 
Create a new environment and try the following.... 
```
pip install mesa
```
