anfo - 0.98-8 main

Anfo is a mapper in the spirit of Soap/Maq/Bowtie, but its implementation takes
more after BLAST/BLAT. It's most useful for the alignment of sequencing reads
where the DNA sequence is somehow modified (think ancient DNA or bisulphite
treatment) and/or there is more divergence between sample and reference than
what fast mappers will handle gracefully (say the reference genome is missing
and a related species is used instead).
