void DampingBoundary	(	PolarGrid *	Vrad,
		PolarGrid *	Vtheta,
		PolarGrid *	Rho,
		PolarGrid *	Energy,
		real	step
	)

Imposes the wave-killing boundary condition.

Currently, the condition is set to always damp the radial velocity to zero. Additionaly, the density, azimuthal velocity and energy can be damped to their initial values.
