Log Message:
4X speedup for peak.model attribute reads.  Unfortunately, they still can
be as much as 40x slower than regular Python attributes.  :(  There's
probably more that could be shaved out, if I write some more Pyrex code.

This change affects how derived attributes are defined: now you override
the 'get()' method instead of '_getList()', which is a lot clearer.
