[BioPython] how to add new methods to class Seq ?

[Jose Borreguero]

Hi all,
I'm new to biopython (and python!), and wondering the efficient way to add
methods of my own to class Seq for my in-house computing. Should I (1) open
the code and start ading add methods; (2) instantiate a derived class from
Seq and write there my methods; (3) what else?
