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.
