That's a good point. So we could move the BCSequenceType ivar to 
BCSymbolSet.

BTW, With the line 'They are not intended to mix' I didn't mean that 
there cannot be user-defined sets. Just meant that I don't see a 
situation where a symbol set is created containing both amino acids and 
nucleotides. That would be 'distorting biology', to use your own words 
:)
