Subclasses are *supposed* to reimplement the methods of a class cluster ...
1. the primitive methods have to be implemented for the classes to function at 
all
2. many/most other methods need to be implemented in terms of the concrete 
ivars actually used ... so we get decent performance.

There shouldn't be any real duplication of code, but there should be a *lot* of 
methods re-implemented ...  to access the 8 or 16 bit character data within the 
strings directly.  These should *not* be 'cleaned out' since they are essential 
for decent performance.
