	<P><B>Description:</B>
	</P>
	<P>Define a computation that calculates the total rotational energy of a
	group of granular atoms.
	</P>
	<P>The rotational energy is calculated as the sum of 1/2 I w^2 over all
	the atoms in the group, where I is the moment of inertia of a
	disk/spherical (2d/3d) particle, and w is its angular velocity.
