The algorithm wasn't accounting for the case where the read is the reverse strand and the insert size is negative.
* Fixed and rewrote for more clarity (with Ryan, Mark and Eric).
* Restructured the code to handle GATKSAMRecords only
* Cleaned up the other structures and functions around it to minimize clutter and potential for error.
* Added unit tests for all 4 cases of adaptor boundaries.
