Actually, I checked something in that takes full advantage of code in both
classes.  The problem was that I had _strict versions that checked for
equality with ==, and regular methods that worked with ambiguous bases.  I
eventually realized that the _strict version was a a good general testing
method.

I took the _strict code, modified it slightly to work with all BCSymbols,
and used that for the range methods in the superclass.  I overrode the range
methods in the DNA subclass to test for ambiguous bases, and I
re-implemented the _strict versions in order to have them call up to the
super's regular method.

I haven't tested the code to make sure it works yet, but it compiles just
fine.
