[Biococoa-dev] Subclass organization

[John Timmer]

Well, I don't really see the point in having complement there when I'm going
to create BCSymbolNucleotide, so I'll just do an experiment when I get into
work tomorrow (where I've got the initial files):  can I move the complement
method to BCSymbolNucleotide and not have anything break, build wise?
