Merge branch 'master' of git@github.com:jhprinz/msm-tis.git
improved storage
corrected errors
updated
Added hull.py (from dynamiq r199).
Updated README to include req'd packages.

Also, corrected my name in conf.py. :-P
Corrected permissions on hull.py. (644, not 755)
Removed _build directory from docs/

This requires that the user build this, ensuring that it isn't out of date
compared to the source in the commit.
Added .gitignore for docs generated in _build.
Removed *pyc files and added them to gitignore.
Corrected URLs in docs/README.md.
Merge pull request #4 from dwhswenson/docs_iss3

Docs (Issue 3)
Draft of hull_volume; minor additions to hull.

I'm keeping the original hull.py file separate so that I can easily sync it
between msm-tis and dynamiq. I've generated a separate hull_volume file for
the msm-tis Volume object version.
Oops; forgot to add hull_volume in previous commit.
Implemented potentially useful methods in hull.py.

* `hull_facets()`: returns vertex numbers to describe the facets on the
  hull.
* `vertex_list_to_points()`: return spatial points for a list of vertices
  (maintaining array shape)
