the cutoff distance should be sqrt(2) + 0.1, since the surfaces of two
particles that far apart could be touching.

NOTE: Do we need a diagram of 2 overlapping polygon particles that
explains how contact is defined?  Do we need an equation(s) that
explain what the params in pair style and coeff mean, for damping and
spring constants?  Or do we just want to reference the paper for that?
The forces between vertex-vertex, vertex-edge, vertex-face and edge-edge
are given by:
