Update log encoder to work with current pipeline
Fix bug with division by int returning 0 (thanks Python). Re-arrage init params for readability
Add numpy for use in closenessScores()
Clean up Log Encoder tests. Add tests for count of buckets, output of closenessScores(), and output of getDecoderOutputFieldTypes(). Fix bug with integer vs scalar division. Remove previous dev cruft.
Implements feedback from @subutai on Log Encoder. Log encoded values are no longer scaled by 10x (not sure why this was done originally). Added better comments, doc string, and tests.
