[Biojava-dev] SymbolList tokenization

[Francois Pepin]

Sorry about the subject-less message earlier.

I added a 'default' SymbolTokenization in the AbstractAlphabet. If none
are defined, it returns the 'token' one else the 'name' one. I didn't
change any of the code used to instanciate alphabets, so any code that
doesn't extends AbstractAlphabet would be stuck.

AbstractSymbolList calls to 'default' for SeqString as well.

Not a perfect solution, but it should make things a bit saner.
