The setup.py file successfully copies aemulus_data.py to the site-packages area, but the data are not. This means that the routines can't actually find the data. Not sure what the best solution is, since we don't necessarily want to copy all the data into the site-packages area, since the data can be large.

In order to make the docs work I reorganized everything so that aemulus_data.py is in the aemulus_data/ directory but as __init__.py. Because of this the routines aren't working. Not a big deal since there isn't much to fix but it needs to be fixed.

At the moment there exist functions to get paths to the cosmologies and data, but not direct function calls. This would make more sense to implement and should be a top priority.
