/**
* ControlP5 Annotation
*
* Lately annotation support has been added to processing.
* Making use of annotations to create controllers is a great strategy i learned
* from Karsten Schmidt's (toxi) cp5magic library.
* Loving the simplicity of annotations and how it is aplied with cp5magic,
* i had to include it into controlp5 and the following example
* shows how to use annotations with controlp5.
*
* Annotations can be applied to variables and functions of the main program
* as well as individual classes. More details are included in the comments below.
*
* by Andreas Schlegel, 2012
