-* Add improved Rigid Body physics engine. We now use [dyn4j](https://dyn4j.org), an open-source Java 2D physics engine. `animationManager` is upgraded (previously it used my own simple physics engine, which couldn't scale to many collisions). Opticka uses degrees, and we do a simple mapping of degrees > meters, so 1deg stimulus is a 1m object.Test it with:

 * Improve touchManager to better use the rigid body animations with touch events. You can now finger-drag and "fling" physical objects around the screen.
 * add Procedurally generated polar checkerboards: `polarBoardStimulus`, and improved polar gratings to mask with arc segments: `polarGratingStimulus`.
 * added new stimulus: `dotlineStimulus` - a line made of dots.
