Exercise 02 - Reverse a String.

Pretty simple, write a function called reverseString that returns it's input, reversed!

reverseString('hello there') // returns 'ereht olleh'

You will notice in this exercise that there are multiple tests, after making the first one pass, enable the others one by one by deleting the x in front of the it() function.
