/************************************************************
Step
This is where knowledge of physical systems comes in handy.
For every vertex the surface tension is computed as the
cumulative sum of the difference between the vertex height and its
neighbors. This data is fed into the change in velocity. The
other values added are for damped oscillation (one is a proportional
control and the other is differential) and so the three physical
quantities accounted for are elasticity, viscosity, and surface tension.
Height is just incremented by time*velocity.
