We already have some in BioCocoa: BCUtilDNATranslator,
Anyway, I am working now on the digest code, and want to make sure that
I get the design right.
1. BCUtilDigest is fed a BCSequence and enzyme information and does the
digest either by an external trigger or internally.
2. It returns an NSArray of BCFragment objects which are wrappers
conatining all info: the sequence, the original location, the enzyme.
Do we need a separate BCUtilDigestProtein, BCUtilDigestDNA?
We have to make sure BTW, that we use the 1-based counting when dealing
