Exercise 6: Almost Palindrome

A palindrome is a series of characters which is the same spelled forward and in reverse. For the purpose of this exercise, a capital letter is equal to its lowercase equivalent. Given a string, return whether or not the string would be a palindrome if one or fewer characters were removed. Return true if it is a palindrome or almost a palindrome, and false otherwise.
