+*  Using the JavaScript language, have the function VowelCount(str) take the str       *
+*  string parameter being passed and return the number of vowels the string contains   *
+*  (ie. "All cows eat grass" would return 5). Do not count y as a vowel for this       *
+*  challenge.                                                                          *

+*  I will be using two for loops that will be nested. I will be searching thru all     *
+*  entries in my vowel array in the outter loop and searching through each letter      *
+*  in the string in the inner loop. I will be comparing each vowel to every letter     *
+*  in the string. If it matches then I will be incrememting by total by 1.

+*    3) Loop through each vowel and compare to each letter in string                   *
+*    4) If match then increment tot by 1                                               *
