Class Summer

Extend from this class to get the capability to maintain 'related sums'. Have a tuple in your class like the following:

   sums=(('amount','credit','credit_total'),
         ('amount','debit','debit_total'))

and the 'credit_total' member of the 'credit' member of self will always be incremented when the 'amount' member of self is incremented, similiarly for the debit versions.
