* ControlP5 extending Controllers
*
* the following example shows how to extend the Controller class to
* create customizable Controllers. You can either extend the Controller class itself,
* or any class that extends Controller itself like the Slider, Button, DropdownList, etc.
*
* How to:
*
* 1) do a super call to the convenience constructor requiring
* 2 parameter (ControlP5 instance, name)
*
* 2) the Controller class has a set of empty methods that allow you to capture
* inputs from the mouse including
* onEnter(), onLeave(), onPress(), onRelease(), onClick(), onScroll(int), onDrag()
* These you can override and include functionality as needed.
*
* 3) use method getPointer() to return the local (relative)
* xy-coordinates of the controller
*
* 4) after instantiation custom controllers are treated the same
* as default controlP5 controllers.
