have autoplay turn off and on by a simple function call

[monu180]

can we have the autoplay feature turn off and on by a simple function call?
like
carousel.autoplay(true); // to turn autoplay on
carousel.autoplay(false) // to turn autoplay off

add to after line 637;

this.stopAutoPlay = function () {
autoPlay(true);
options.autoPlay = 0;
};

this.startAutoPlay = function () {
autoPlay(false);
options.autoPlay = 1;
};
