[Biococoa-dev] more on Peptides

[Charles PARNOT]

The difference in speed does not look significant to me, so yes, we could use a BCPeptide class if this is useful!

To see if this would make a speed difference, I added a new class to the target, Peptide, which now is a subclass of BCSequenceProtein.  Also in the theController.m I had to make some changes, however, I have bracketed these with a #define that can be set to 0 or 1 to use the Peptide or Result class, respectively. It is located at the top the theController.m:
