// Frame Events Example with two frame loops controlling two 
// MovieClips, cycle1 and cycle2, on two different frames. 
//
// On frame 1, a frame loop repeatedly goes to frame 1 and stops,
// so that only frame 1 will play repeatedly and move cycle1
// On frame 2, a frame loop repeatedly goes to frame 2 and stops,
// so that ony frame 2 will play repeatedly and move cycle2 
// A button controls when the action moves from the first frame
// to the second frame. Before moving to the second frame, the 
// button handler removes the frame 1 ENTER_FRAME listener.
// After moving to the second frame, it adds the frame 2  
// ENTER_FRAME listener.
