// Customer.cpp
// Implementation:
// -- Customers hold a 4-digit unique id a last name and a first name.
//    Customers will be held in a hash table for quick look up and retrieval.
//    Customers will also be in charge of holding their own Transaction
//    history with the use of STL stack for LIFO.
// Asumptions:
// -- The data file will be formatted correctly, as well as id's will be a
//    unique 4-digit number.
// -- Customers keep track of thier own Transaction history
// -- STL stack is used to LIFO display Transaction history
