#Write a program that repeatedly prompts a user 
#for integer numbers until the user enters 'done'. 
#Once 'done' is entered, print out the largest and 
#smallest of the numbers. If the user enters 
#anything other than a valid number catch it with 
#a try/except and put out an appropriate message 
#and ignore the number. Enter 7, 2, bob, 10, and 
#4 and match the output below.
