/* Palindrome words
Create the function that accepts the target string and returns true if it's a werewolf or false if it isn't.

A werewolf is a word or sentence that you can read the same in both directions (left to right and vice versa) ignoring case, spaces, and punctuation.

For example:

isWerewolf('rotator'); // true ('rotator' -> 'rotator')
isWerewolf('home'); // false ('home' -> 'emoh')
isWerewolf('Racecar'); // true (case is ignored)
isWerewolf('eva, can i see bees in a cave'); // true (spaces and punctuation are ignored)
