In this assignment, a transfer method has been added to the ATM class of section 12.5:

public class ATM 
   /** 
      Transfers between the current account and the other account
      of the same customer.
      (Precondition: state is TRANSACT)
   */
   public void transfer(double value)
   {
      . . .
      back();
   }

Your task is to change the command-line user interface of the ATMSimulator so that the menu

A=Deposit, B=Withdrawal, C=Cancel: 

is replaced by

A=Deposit, B=Withdrawal, C=Transfer, D=Cancel: 

Of course, you should now carry out the appropriate actions when the user selects options C or D.
