The basic setup is something we all agree on I think, it would be nice 
indeed if all classes had the same BCSequence prefix, although not easy 
;-) I like BCSequenceBundle, but I'm not sure if wrapper is 
appropriate. I know we consider it a wrapper object, but I would like 
to keep it closer to sequences, I thought of BCAnnotatedSequence, but 
it would loose the common prefix. Still, better than BCSequenceWrapper. 
Anyway, the (semi-)native englishmen on this list can jump in here ;-). 
Wait, would it be an idea to make it:

BCAnnotatedSequenceBundle - a bundle of BCAnnotatedSequences (in an 
array)

BCAnnotatedSequence - contains a dictionary of BCFeatures (so no 
BCFeatures object, because that has no advantage over a dictionary), a 
BCSequence, a dictionary of BCAnnotation

BCFeature - a feature
BCAnnotation - a non-feature annotation (notes, authors, links, etc etc)
These two resemble BioPerls setup

Then it's a stupid developer IMHO....
