Make a Function on the Treasure Controller to Reset the Whole Game

Next, we’ll make a function for the TreasureControllerScript to reset the game, and let it send a signal to the chest to reset itself. 

1. Give the TreasureControllerScript an EntityRef for the Chest-Bottom entity.
2. Create a new function called resetGame
3. Create a new variable for the chest, using get on the chestRef
4. Check that the chest  is not null.
5. Send an event to the chest with “reset”.
