26 * Very crude pig latin converter.
27 * Piglatin is an encoded form of English that is often used by  children
28 * as a game. A piglatin word is formed from an English word by:
29 *
30 *  .	If the word begins with a consonant, move the consonant to the end of
31 *	the word and append the letters "ay". Example: "door" becomes "oorday".
32 *
33 *  .	If the word begins with a vowel, merely append "way" to the word.
34 *	Example: "ate" becomes "ateway
