  needs to organize and track a series of Transaction objects. See the Transaction class file.
  Transaction needs to use a few Payee objects for your tests.
  
- * int size()
- * boolean isEmpty()
- * boolean contains(Transaction element)
- * boolean add(Transaction element)
- * boolean remove(Transaction element)
- * Iterator<Transaction> iterator()
+* int size()

  AND
  
- * Transaction[] toArray()
- * <Transaction> Transaction[] toArray(Transaction[] a)
+* Transaction[] toArray()

- * double checkbookValue() // sum of all Transactions (both Debits and Credits)

 finally, make a generic account class, that takes any class which implements the AccountBook interface.
