Investigate what JS unit test library should be used and begin implementing unit tests

If Rotating Right twice, LongRectangle moves to the left by one position

If Rotating Left twice, LongRectangle moves up by one position

I'm not sure I want to consistently have to commit updates to either of these files every time javascript or scss files are updated.

Upper right square box should be populated with the Next Piece that in in the play queue.

This will provide us with the ability to identify the amount of copy-and-paste code utilized in this application and help reduce this as much as possible.

Also, investigate whether we can advertise this metric to viewers of this github repository (if needed, we can always create a separate ticket to implement this metric exposure task)

Refactor the movement of pieces so that functions like getBottomMostSquares(), getLeftMostSquares(), getRightMostSquares() aren't utilized by the CanvasManager to check if a piece can actually be moved down, left or right, respectively.

Instead, we should create functions like getSquaresAfterMovingDown() implemented in BasePiece and then check if we can do so via the canSquaresBePainted() function within CanvasManager.
