17/* USAGE
18
19// listen both left and right signals, the String "left" or "right" will be passed as an argument to the callback
20* $(element).touchSwipe(callback); 
21
22// second parameter is optional and will invoke "event.stopImmediatePropagation()" 
23// use this if you need to prevent other mouse events from firing on the same object when a swipe gesture is detected
24* $(element).touchSwipe(callback, true);
25
26// listen for only the left swipe event
27* $(element).touchSwipeLeft(callback); 
28
29// listen for only the right swipe event
30* $(element).touchSwipeRight(callback); 
31
32// unbind both left and right swipe events
33* $(element).unbindSwipe(); 
34
35// unbind only left swipe event
36* $(element).unbindSwipeLeft(); 
37
38// unbind only right swipe event
39* $(element).unbindSwipeRight();
40 
41
42// SPECIAL NOTES 
43* all methods return "this" for chaining
44* before a plugin event is added, "unbind" is called first to make sure events are never erroneously duplicated
