Part 2: Name and Email Addresses

Write a program that keeps names and email addresses in a dictionary as key-value pairs. The program should display a menu as shown in the sample output(s) that lets the user look up a persons email address, add a new name and email address, change an existing email address, and delete an existing name and email address. The program should pickle the dictionary and save it to a file named as emails.dat when the user exits the program. Each time the program starts, it should retrieve the dictionary from the file and unpickle it. When the program starts for the first time, the file doesnt exist and thus it needs to create an empty dictionary.
