val create : Board.t -> seconds_per_sweep:float -> t

(* [cur_pos] returns the current position (column) of the sweeper. *)
val cur_pos : t -> int

(* [seconds_per_step] returns how quickly the step function should be called to
   make it sweep the board in the time given by seconds per sweep. *)
val seconds_per_step : t -> float

(* step advances the sweeper one square and potentially removes squares from the board *)
