Restitution calculations don't fit well into a system based on impulses where
penetration is accepted and effectively ignored. If collisions were swept and
hence
perfect the current system would provide restitution - however, the trade off
between
simplicity and perfect elastic collision seems fair as is. This physics system
will
not work for *true* simulations where swept collision should be used.

Scratch the rubbish above. Restitution is implicit in the original demo - a
resitution of zero. Restitution has now been added correct and works well in
demos.
Also added Body.getEnergy() and World.getEnergy() to evaluate the total energy
in the
system. This aids in ensuring resititution is correct.
Changes to engine and demos made in Revision 16.
