A simple extension of the javascript Number class for ease of generating random numbers.

	// Example use
	// var arr = [1, 2, 3, 4, 5];
	// var len = arr.length;
	// var item = arr[len.random()];

	Number.prototype.random = function(inc) {
	var val = (inc) ? 1 : 0;
	return Math.floor(Math.random() * (this.valueOf() + val));
	};
