Usage

import com.processinghacks.arcball.*;

// inside setup()

// for a default arcball
// centered on width/2, height/2, -min(width/2,height/2)
// with radius min(width/2,height/2)
Arcball arcball = new Arcball(this);

// or to specify center x/y/z and radius
Arcball arcball = new Arcball(100,100,0,50,this);
