// USAGE EXAMPLE
// var myNumber:int = 2319854;
// trace("myNumber: " + myNumber);
// var myNumberWords:String = NumberUtil.converToWords(myNumber);
// trace("myNumberWords: " + myNumberWords);
//
// OUTPUT
// myNumber: 2319854
// myNumberWords: Two Million Three Hundred Nineteen Thousand Eight Hundred Fifty Four
