I am not in favor of them too, just check the archives for some nice 
discussions :)

I would really strongly suggest not to drop the BCSymbolSet classes. 
They define the type of sequence we are dealing with and also function 
as a datafilter to make sure that only the correct symbols are added to 
a certain sequence.

That being said, why do you put the word 'annotation' in these classes? 
I think that's what is confusing me, especially you meant them to be a 
replacement for BCSymbol.
