/*
2009-04-26, 0.9.10
- Allow to set a threshold for local alignment
2009-02-18, 0.9.9
- Fixed a bug when no residue matches
2008-08-04, 0.9.8
- Fixed the wrong declaration of aln_stdaln_aux()
- Avoid 0 coordinate for global alignment
2008-08-01, 0.9.7
- Change gap_end penalty to 5 in aln_param_bwa
- Add function to convert path_t to the CIGAR format
2008-08-01, 0.9.6
- The first gap now costs (gap_open+gap_ext), instead of
gap_open. Scoring systems are modified accordingly.
- Gap end is now correctly handled. Previously it is not correct.
- Change license to MIT.
