*  Have the function AlphabetSoup(str) take the str string parameter being passed      *
*  and return the string with the letters in alphabetical order                        *
*  (ie. hello becomes ehllo). Assume numbers and punctuation symbols will not be       *
*  included in the string.                                                             *

*  The Array has a built-in sort function but String does not. The first step is to    *
*  convert the string to an Array and sort it in alphabetical order. Then covert the   *
*  Array back to a string with the join() function.                                    *
*                                                                                      *

*    1) Convert string to an array                                                     *
*    2) Sort array in alphabetical order                                               *
