Add a Time Deposit Account class to the bank account hierarchy. The time deposit account is just like a savings account, but you promise to leave the money in the account for a particular number of months, and there is a $20 penalty for early withdrawal.

If the count is positive during a withdrawal, charge the withdrawal penalty.
