bio parser

[bioinfornatics]

Dear,
I wrote a fasta format parser and fastq format parser. These parser used
MmFile and do not load all file these will save memory.

Fastq http://dpaste.dzfl.pl/9b23574d
Fasta http://dpaste.dzfl.pl/228dba11

The way to iterate over it is really close and i search a way to have
one struct bySection one template doIndex for both file format.

If you have any suggestion to improve this, please tell to me.

thanks
