/**
 * Simulates the higher user level gesture of the given name on this node. 
 * This method generates a set of low level touch events(Apple specific gesture 
 * events as well for the iOS platforms) asynchronously. Note that gesture  
 * simulation is relying on `Y.Event.simulate()` method to generate 
 * the touch events under the hood. The `Y.Event.simulate()` method
 * itself is a synchronous method.
 * 
 * Supported gestures are `tap`, `doubletap`, `press`, `move`, `flick`, `pinch`
 * and `rotate`.
 * 
 * The `pinch` gesture is used to simulate the pinching and spreading of two
 * fingers. During a pinch simulation, rotation is also possible. Essentially
 * `pinch` and `rotate` simulations share the same base implementation to allow
 * both pinching and rotation at the same time. The only difference is `pinch`
 * requires `start` and `end` option properties while `rotate` requires `rotation` 
 * option property.
 * 
 * The `pinch` and `rotate` gestures can be described as placing 2 fingers along a
 * circle. Pinching and spreading can be described by start and end circles while 
 * rotation occurs on a single circle. If the radius of the start circle is greater 
 * than the end circle, the gesture becomes a pinch, otherwise it is a spread spread.
 *

 *
 *     var node = Y.one("#target");
 *       
 *     // double tap example
 *     node.simulateGesture("doubletap", function() {
 *         // my callback function
 *     });
 *     
 *     // flick example from the center of the node, move 50 pixels down for 50ms)
 *     node.simulateGesture("flick", {

 *         duration: 50
 *     }, function() {
 *         // my callback function
 *     });
 *     
 *     // simulate rotating a node 75 degrees counter-clockwise 
 *     node.simulateGesture("rotate", {
 *         rotation: -75
 *     });
 *
 *     // simulate a pinch and a rotation at the same time. 
 *     // fingers start on a circle of radius 100 px, placed at top/bottom
