     * opposite of a concert where the closer you are the cheaper you're seat is. This is accurate since the middle and end
     * seats are typically preferred in a movie theater.
     * Users of this program can pick a row and and number of seats per row. Then they are given the option to reserve
     * and purchase them.

	/** If I had more time, I would implement:
	 * 
	 * A database to store Ticket purchasing info.
	 * A web service to email and confirm with the customer. A http request API to email confirmations and store user confirmations.
	 * A UI Framework in JavaScript or Java FX to make the ticket purchasing easier.
	 * Seating Rows can be labeled, but the price kept the same.
	 * Lastly I would include a timer on the reservations.
	 * 
	 * I did enjoy this exercise a fair bit and look forward to working on more!
