Picard release 1.117
14 July 2014

- Added a divide function to Math.Utils.

- Remove from Picard libraries that are found in htsjdk, since we can 
use those, as we are tightly coupled to htsjdk.

- Updated RnaSeqMetricsCollector to make coverage collection optional.

- Add travis-ci to Github project.

- Explicitly implement Closeable on classes and interfaces with close().

- Enhance TabixReader: iterator moved to interface.

- Added the Damerau-Levenshtein algorithm to calculate a distance 
between strings into StringUtil.

- GitHub-51: Fix NPE if idxFn TabixReader ctor arg is non-null.

- ReferenceSequenceFileWalker.java: Checks if ReferenceFile is indexed, 
and if so, uses it
