Update documentation format for implemented methods

[paulmthompson]

Since there is so much redundancy in the literature, I really want to try to identity methods by what they do rather than just associating them with one paper or another (although they will be appropriately cited!). For instance, the "OSort" clustering I have right now should really be called "adaptive centroid" or something and cite OSort. For some data science algorithms, like CLASSIT, this will be unavoidable.

The documentation needs updated for the methods that are currently implemented need to be better described and probably re-titled.
