Title: Adds initial cut of TopicModelUtils class

This class contains a basic impl of topic-term matrix sparsification routine discussed with Jake.

Does not yet support parameterization of sparsification logic. Wanted to get this written in the most direct way first, test it, then consider options for generalization.
