This QueueStackUtil class tests various usages of the Queue interface and Stack classes
param1 is a string. You will push each of its characters onto a stack, then as you pop
off the characters, you will compare them to to the characters of th string in forward
order. If ALL the characters match, you will return true because the string is a
palindrome, oherwise you will return false.
