/**

* Intro

* To solve this challenge, feel free to use any and all resources available to you. Once you start the exercise, you'll have two hours to complete and submit your solution.

* Challenge - Pig Latin

* Pig Latin is a farcical "language" used to entertain children, but also to teach them some valuable language concepts along the way. Translating English to Pig Latin is simple:

* 1) Take the first consonant (or cluster of consonants) of a word, move it to the end of the word, and add a suffix of "ay" 2) If a word begins with a vowel, just add "way" at the end 3) For the sake of readability, separate the Pig Latin-ized parts of the word with a dash -

* Your challenge is to implement the method pigLatinize that takes a string phrase and translates it to Pig Latin. You're free to add additional classes, variables, and methods if you would like.

* The input phrase could be as short as a single word, or as long as multiple sentences or paragraphs. Whitespace, capitalization, and punctuation should be honored and maintained in your final answer.

* Examples

* 1) "pig" => "ig-pay" 2) "pig latin" => "ig-pay atin-lay" 3) "Pig Latin" => "ig-Pay atin-Lay"

// we set it as 0. Otherwise, we use the last space index to move

// the previous space index one step ahead
