We're going to write a program that manages the email address of our contacts.

Your program must contain a class named contact that has $3$ attributes

$($instance variables$)$: last name, first name, and email. Your class should also

have a method to return the full name and email address for printing when

requested. You may add other methods to the class if you like.

Please start early in the week that this program is due; this gives you plenty of

time to ponder how is should work. Moreover, there will be more to ponder as

the course progresses. I am glad to help troubleshoot programs, but I go to bed

reasonably early and am unlikely to stay up until midnight of the due date.

Each contact should use a single instance of your contact class. You should use

either a list or a dictionary to act as a container of the contact instances.

Also, the program should have a menu that allows the user to interact with your

collection of contacts: displaying contacts or adding new contacts as long as the

user wishes, then saying goodbye when finished. The menu should offer these

options. Note we are not saving anything to disk here.

Program Options.

$1.)$ Display all contacts

$2.)$ Create new contact

$3.)$ Exit
