/* Further Adventures

 *

 * 1) Run the program.

 *

 * 2) At the console prompt,

 *    try to use Player to create a new

 *    player object.

 *

 *    > var p = new Player("Dax", 50)

 *

 *    It won't work.

 *    Player is a private variable.

 *

 *    However, Player has also been assigned

 *    to theCrypt, which is global.

 *

 * 3) At the console prompt,

 *    use theCrypt.Player to create a new

 *    player object.

 *

 *    > var p = new theCrypt.Player("Dax", 50)

 *

 *    Okay, it can now find Player.

 *    But spacer has gone AWOL.

 *

 * 4) Add a script element to the HTML Panel

 *    to include the spacer namespace.

 *    (JS Bin code for spacer: juneqo)

 *    (You may have to refresh the page

 *     to load the script.)

 *

 * 5) Create a new player and call p.showInfo()

 *
