This adopts a "writer" concept, vaguely inspired by the ta parameter writer. This might turn out to be not a great idea if the response/offsets for heterogenous commands are too inconvenient to keep track of. This breaks every example that uses maple--only example/maple_controller is updated to use the new interface.
