Bug fixes and license switch

We recommend that users switch to this release because of a few bug fixes.

• Wrong strand reported when fusions are only supported by pairs and no split reads
• Bug with negative coordinates fixed
• Bug fixed when reference sequences had lower case characters
• Correct order of geneA and geneB in JSON output

Additionally we now have a scripts folder with useful python scripts

• get_fragment_length.py examines an abundance.h5 produced by kallisto and finds the 95th percentile of the fragment length distribution
• flatten_json.py reads the .json output and converts to a simple gene table
