• Design a class Customer that requires a name, customer ID, address and phone number.
• Using doubly linked lists, create a list of customers in order by customer id. Create a menu-driven program to provide the following options:
  • Add a new entry to the customer list.
  • Delete an entry from the customer list
  • Display the list in forward or reverse order.
• Be sure to clean up any unused/deallocated nodes as you remove items from your list.
