/* Further Adventures

 *

 * 1) Run the program.

 *

 * 2) Create a place.

 *

 *    > var p = new theCrypt.Place("The Farm", "You are at a farm.")

 *    > p.showInfo()

 *

 * 3) Add an exit.

 *

 *    > p.addExit("east", "The Farmhouse")

 *    > p.showInfo()

 *

 * 4) Create a challenge object.

 *

 *    > var ch = {}

 *    > ch.message = "There is a bull blocking the gate"

 *    > ch.success = "The bull runs off after the kite"

 *    > ch.failure = "It's getting angrier"

 *    > ch.requires = "a red kite"

 *    > ch.damage = 30

 *    > ch.itemRequired = true

 *    > ch

 *

 * 5) Add the challenge.

 *

 *    > p.addChallenge("east", ch)

 *    > p.getChallenge("east")
