It's not intended to be a subclass of NSMutableArray, but it has an
NSMutableArray as it's only member. The idea is to have a bare-bones
class that *only* maintains an array of BCSymbols but without all the
overhead of features and annotations. These can be handy for searching,
and specific calculations.
So it could have the following methods from the current BCSequence:
initWithArray
symbolAtIndex
subSequenceStringInRange
etc.
but not:
sequenceType
symbolSet
name
The current BCSequence will be a subclass of this new class, and will
have members for features and annotations.

Well, that can be done with or without the BCSymbolList anyway.
