/*  --  Problem  --
 *  Have the function alphabetShift(str) take the str parameter
 *  being passed and modify it using the following algorithm.
 *  Replace every letter in the string with the letter following it
 *  in the alphabet (ie. c becomes d, z becomes a). Then capitalize
 *  every vowel in this new string (a, e, i, o, u) and finally return
 *  this modified string.

/*  mergeSort
 *
 *  basic idea is as follows:
 *  break an array of integrers into pieces recursively
 *  and merges it back together using its sorted pieces
 *
 *  this implementation uses "take from the front put in
 *  the back" logic while merging
 *
