CharAt Function
This function returns the character at a given position(index) in a string.
While it's a fairly simple thing to do, and we have the StringInStr and StringMid native functions which can be setup to get the same result, sometimes what we need is a simple approach to this. I hope any of you can find it useful.

;Given a String and an Index, returns the character at that position.
