/* Further Adventures

 *

 * 1) Run the program.

 *

 * 2) At the console prompt, type the following,

 *    pressing Enter after each one:

 *

 *    > var mapData = theCrypt.mapData

 *    > mapData

 *    > mapData.title

 *    > mapData.places

 *    > mapData.places[0]

 *    > mapData.places[0].description

 *

 * 3) Create a new empty place and assign it

 *    to a variable.

 *

 *    > var place = {}

 *

 * 4) Add title and description properties

 *    to the place.

 *

 *    > place.title = "The Games Room"

 *

 * 5) Add the place to the mapData places array.

 *

 *    > mapData.places.push(place)
