	The goal of the task is to recall numbers randomly placed on a grid of tiles (board) in accending order.
	To finish a game of any level sucessfuly, the participantd must complete the goal without
	any error. After which a new board will appear.

	If an error is made a buzz sound will occur and a new board will be displayed.

| Know Bugs and Improvements |
 ----------------------------
 
 Bugs:
 - Error when csv file being recorded to is open in another program
 
 Improvements:
 - Need to change how the board is constructed on the client end to improve loading speed. Right now each tile is requires a async call to the server. Changing the board generating to initially occur on the client end may speed things up.
