  5.  * Compute Savings Balance
  6.  *____________________________________________________________________________
  7.  * This program will calculate the balance of a savings account after a period
  8.  * of time, taking into account annual interest rate, the starting balance, 
  9.  * and the number of months that have passed since the account was established.
  10.  * 
  11.  * Formulas Used:
  12.  * monthlyRate = annualRate / 12.0
  13.  * monthlyResult = balance * monthlyRate
  14.  * ____________________________________________________________________________
  15.  * Input
  16.  *   annualRate        //The annual interest earned in the savings account
  17.  *   startingBalance   //The starting amount in the savings account
  18.  *   months            //The amount of months that have passed 
  19.  *   deposit           //The amount deposited into the acount each month
  20.  *   withdrawl         //The amount withdrawn from the account each month
  21.  * 
  22.  * Output
  23.  *   balance           //The total within the account after the time entered has passed
  24.  *   monthlyRate       //The rate of interest calculate per month based off of annual interest
  25.  *   monthlyResult     //The total amount of interest gained per month based off of the balance
  26.  *   totalDeposit      //The total amount deposited into the account after so many months
  27.  *   totalWithdrawl    //The total amount withdrawn from the account after so many months
  28.  *   totalInterest     //The total amount of interest earned after so many months
