Description:
-----------
 The tick mark module creates sheets with major and minor line grids
 along the three primary axes. It makes polytriangle objects, not
 lines, so they can have variable thickness. It also has label
 annotation on the 3D object.

 I took my graphcorr.c module and turned it into a program which
 makes tick marks for a given region.  Setting up a stage if you
 will.
