今週は2回目のブラックジャックゲーム。
行数が多いので見にくい。JavaScriptにはJavaのimportにあたるような機能はないのかな？

	// 1. Putting Objects to Use
	// make a Card constructor here. It should take two parameters
	// representing the suit and number of the card to be created
	function Card(suit, number){
	this.suit = suit;

	// representing the suit and number of the card to be created
