* ControlP5 Behavior
|
|
* ControlBehavior is an abstract class that can be extended using your

|
* custom control behaviors. What is a control behavior? Control Behaviors
|
|
* allow you to automate and dynamically change the state or value of a
|
|
* controller. One behavior per controller is currently supported. i case you
|
|
* need to use more that one bahavior, the implementation has to happen
|
|
* on your side - inside your control behavior.
|
|
*
|
|
* find a list of public methods available for the ControlBehavior Controller
|
|
* at the bottom of this sketch.
