Preliminary implementation of frequency table

Began implementation of frequency table from Mallet output.

Added batch file to train 10 topics (at Yue's request).

Must run import.bat and traintopics10.bat before executing this project.
Accesses generated file topic-state.gz and extracts topic information
into a HashMap. Not sure if this is the best structure for the task.

Stopped here because I'm not sure what the plan is for multiple users
and multiple topics (seem to remember having to generate a structure for
each user for each topic). Low-level functionality (structure creation
and population) functioning.
Merge branch 'master' of https://github.com/jordanhennell/AAR
