fix NaN bug with empty messages in 1-segments
Small bugfixes and cleaning - I had tried out a small change in HeatSeg.isLocalMin()
to eliminate the hacky try/catch block, but it started throwing NullPointers randomly
so I put the old code back and commented the experimental code. I'll work on that
shortly.
add print of cohens kappa and tests
Cleaned majority of the code, added more comments
and reworked some conditionals to make more sense.
Debug statements are now more verbose.
Removed --infer-occurrences option.
Changed occurrence from primitive float to reboxed Float type.
  This allows the value to be initialized to null, and then checked later on down the line.
Merge branch 'master' of github.com:etcgroup/aloe into dan-dev
Added newlines to the Positive and Negative Predictions fields.
