   Harmonic Sloshing experiment.

   Here we start with a harmonically trapped gas, we then display the trap center so
   that the gas sloshes back and forth.  This should result in purely sinusoidal
   center-of-mass (CoM) motion.  Next, we add a small bump.  In the presence of
   viscosity, this should dissipate energy, causing CoM amplitude to decrease.

   We use this decrease as a way of measuring the effective viscosity in a superfluid
   which has strictly no energy loss.

   Experiment for Finite-Volume SWE.
   M = amu, L = microns, T = 1/Hz.
