[Biojava-l] Refactoring TranslationTable/ReversibleTranslationTable/RNATools

[David Huen]

I have derived AbstractTranslationTable and 
AbstractReversibleTranslationTable classes from existing code and 
reimplemented the above classes over these classes.  The code seems to pass 
all existing tests but if you should observe peculiar behaviour, please do 
report it here.

These changes are in preparation for support of codons/codon frequency 
tables/etc which may best belong in a CodonTools class perhaps?  Logically 
then, the getGeneticCode() call should move to CodonTools but that will 
break things.  A ManyToOneTranslationTable class may be required to support 
returning a List of codons that encode a particular residue.

David Huen
