	Well one thing that is annoying is that when I do a
AlphabetManger.getCrossProductAlphabet(list Degenerate DNA alphabet) I get
back an immutable Alphabet, so I cant add gap^3, unless I want to add
gapXDNAXDNA, gapXgapXDNA etc. To make matters worse it is a sparse alphabet
(~4000 symbols), which is an alphabet, not a finite alphabet, so I can't get
all the symbols to create a new alphabet that includes the gap^3. 
	ok, so I probably just have to create a new alphabet on my own, I
just didn't want to.
