DESCRIPTION

Symmetrize inputs a list of r and z values ( cylindrical coordinates )
which define a axisymmetric object.  The input field is only 1-D, but
it is a vector field with the first scalar in each vector being the r
value, and the second scalar in the vector field being a corresponding
z value.  Symmetrize inputs the list, performs NO sorting, and then constructs
a mesh object around the Z axis.  The mesh is constructed by distributing
a series of nodes around the Z axis, equally spaced by the divisions parameter.
( i.e. if divisions is 4, then a mesh node will be placed every 90 degrees. ).
4 vertice polygons are then constructed among the distributed nodes.

APPLICATION

This module is very useful in creating any axisymmetric object.  We initially
used it for the visualization of a while blood cell shape deformation algorithm.
