## NumberGuess mini-game: 

### Description
This is a very simple number guessing game. Minecraft will ask you to
guess a number between 1 and 10 and you will tell you if you're too
hight or too low when you guess wrong. The purpose of this mini-game
code is to demonstrate use of Bukkit's Conversation API.

### Example
    
    /js Game_NumberGuess.start(self)

Once the game begins, guess a number by typing the `/` character
followed by a number between 1 and 10.
