a pickle's pickle

[temposs at gmail.com]

I intended to pickle the class instance I call trainer...from my code,
also in the first post:

trainerString = trainDB.read()
        trainer = loads(trainerString)


    except EOFError:
        trainer = TrainingMatrix()
...
trainerString = dumps(trainer)
...

So basically trainer always gets an existing TrainingMatrix(the class)
pickled object if there is a file to read from, otherwise it just makes
a new instance.  Either way, the instance trainer is pickled at the
end.  Maybe I'm missing something...
