hanna c63af32fc7 The BWA/C bindings were triggering the local aligner to repeatedly reload the 
ref genome.  Make sure the reference genome is cached.

hanna 1f0d852a48 Fix bug where alignments with indels would be busted because bwa reverses 
the read bases to undo a previous read base reverse that doesn't occur in the
libbwa codepath.
Also fixed some memory management issues.

hanna c9a3707cfd Initial version of BWA/C bindings. Still lots of squirrels roaming the code. 
- Some cigar strings aren't right.
- Memory leaks.
- BWA codebase changes aren't committed to BWA tree.
- Aligner interface butchered to support BWA/C-style alignments.

hanna f37564e63a Our BWA is now looking at roughly the same number of candidate alignments as BWA/C. Performance is now at 11k reads / min, still a long way from BWA/C.

hanna b0ec7fc144 More comprehensive testing of BWT (mismatches only) module, and lots of bug fixes. 
Limitations:
1) Can't handle RC alignments.
2) Can't handle indels.
3) Can't handle N's in reference bases.
4) Stops at first hit.

Ran BWT over a test suite of 800k Ecoli reads.  After removing alignments with indels / reads with Ns, the remaining reads were aligned with quality 'equal to' that of the alignment stored in the BAM file.  In this case 'equal' quality is <= mismatches to the reference as the existing alignment stored in the BAM file.

hanna c186a49d55 Time for a reorganization. Repackage generally useful alignment classes lower in the package structure, and create a subpackage for bwa-specific code. Repackage BWA alignment code away from BWT representation. Isolate byte- and word-packing streams in another package that will ultimately be killed off en masse.
