/*
BankSystemDriver.cpp: BankSystem is a project that allows users to dynamically look at and change particular values of their bank and credit accounts.  Upon execution,
                      the user is given a number of choices for actions to take.  They are allowed to validate their card (and identify it), check their balance, enter
                      a new account into the system, or remove an account from the system.
