[Biococoa-dev] BCSymbolSet problem

I am having some trouble getting to populate a BCSymbolSet. I am using 
the code that was originally committed by Alex, and changed it so that 
BCSymbolSet now is a subclass of NSMutableSet.  To populate a set, I 
put some code into the dnaStrictSymbolSet and initwithString methods. I 
also added two lines in the translation demo. You need to uncomment 
them to debug the symbolset code. Everytime I reach the line addSymbol, 
the program raises an exception.

I have no idea why this is happening, so if you see what I am doing 
wrong, let me know!

There is another problem with the current approach. initWithString is 
now hardcoded to create a BCNucleotideDNA, but what  if the method is 
called for RNA or a protein? Not sure yet how to solve this. We might 
need to take a different approach after all.
