/* Modify contol/VowelsAndConsonants.java so that it uses three enum types:
* VOWEL, SOMETIMES_A_VOWEL, and, CONSONANT. The enum constructor should
* take the various letters that describe that particular category. Hint: 
* use varargs, and remember that varargs automatically creates an array
* for you.
