extract.py

Create a new fasta file containing the subset of sequences
defined in list. Neither file need be in any particular order. 
Sequences in list but not in fasta are ignored.

-l             Sequences to include in the new file. Names must
               match those in fasta (not case-sensitive).
-inv           Invert - exclude (rather than include) specified
               sequences.
-out           Name of outfile; writes to stdout if omitted
-strip         Remove gap characters from sequences.
-sort          Sort the sequences in the output file alphabetically.
-h             Print documentation
-d             Turn debugging on
-version       print version info and exit
