   * <strong>Stalactite</strong> is a subclass of
   * {@link adventurejs.Climbable|Climbable}.
   * It hangs down from the ceiling and
   * player can climb on/to/from.
   * See its position.y and its height
   * properties in this example.

   * See that the stalactite's position.y is 3 units high, presumably
   * at ceiling height, and that its height is -1, meaning that
   * it hangs down 1 unit from the ceiling and reaches to 2 units
   * above the ground, out of reach of the player.
