Improve interpolating activities with other easing functions

[GoogleCodeExporter]

PInterpolatingActivity has only one easing mode, setSlowInSlowOut.  Several
other easing interpolation functions exist, such as those made familiar by
Robert Penner:

http://www.robertpenner.com/easing

E.g.

linear
ease-in-quadratic
ease-out-quadratic
ease-in-out-quadratic
ease-in-cubic
ease-out-cubic
ease-in-out-cubic
ease-in-quartic
ease-out-quartic
ease-in-out-quartic
ease-in-quintic
ease-out-quintic
ease-in-out-quintic
ease-in-sine
ease-out-sine
ease-in-out-sine
ease-in-exponential
ease-out-exponential
ease-in-out-exponential
ease-in-circular
ease-out-circular
ease-in-out-circular
ease-in-elastic
ease-out-elastic
ease-in-out-elastic
ease-in-back
ease-out-back
ease-in-out-back
ease-in-bounce
ease-out-bounce
ease-in-out-bounce

It should be possible to plug any of these easing interpolation functions
into PInterpolatingActivity, a subclass of PInterpolatingActivity, or a new
interpolating subclass of PActivity.

YES! I'd 
- add an Interface PInterpolation with the interpolating function
- inject it right into PInterpolatingActivity
- factor the current (linear) interpolation into an implementation of the 
interface
and make it the default
- add several other interpolations to extras

If we want to change the namespaces from edu.umd.cs... to org.piccolo2d (we do, 
don't
we?) we should think about the future package structure and already add the new
classes there.

Latest for 2.0, but maybe already in 1.3?

BTW: there's a nice demo here: https://scenegraph-demos.dev.java.net/demos.html

I am glad there is interest.

My implementation, currently licensed as LGPL version 3 or later, is at

http://dishevelled.svn.sourceforge.net/viewvc/dishevelled/trunk/piccolo-ease/

with dependencies

http://dishevelled.svn.sourceforge.net/viewvc/dishevelled/trunk/interpolate/
http://dishevelled.svn.sourceforge.net/viewvc/dishevelled/trunk/functor/

and example

mples/

See attached runnable jar.

At this point I'm happy with the code as-is in my own repository.  I move to 
mark
this issue as WontFix.
