	Lab 10 Problem 6

	This program utilizes the string class to recieve a string from a user and then determine
	whether it is a palendrom or not.


	Test Suite:

	Input: aba
	Expected Output: aba is a palendrome


	Input: computer science
	Expected Output: computer is not a palendrome

	
	Input: poop
	Expected Output: poop is a palendrome


	Input: Rowan
	Expected Output: Rowan is not a palendrome


	Input: abbbaabbba
	Expected Output: abbbaabbba is a palendrome


	Input: 11113
	Expected Output: 11113 is not a palendrome


	Input: 11211
	Expected Output: 11211 is a palendrome


	Input: word
	Expected Output: word is not a palendrome



	All of the sample inputs within this test suite were tested and performed as expected.
