first attempts at switching blastn away from blast-2-seqs
first draft of parsing -outfmt 5.  Still not complete.
Finished v1. Takes in a -outfmt 5 blast file and makes a fasta of the best matches in it.
tiny script to sort a fasta file by size, largest first.
Merged changes from blast_to_ref_xml into blast_to_ref.
don't die on not finding a vcf file.
trying to get it to not die if the file doesn't exist.
Adding ability to write out separate fasta files for each reference sequence.
Change blast command to blastn instead of megablast.
Lots of improvements.
Merge branch 'redo-blast_to_ref'
