2. Outer Cartesian Box Specs:
      Xmin     Xmax            Ymin    Ymax            Zmin     Zmax
      -40.0    40.07           -40.0    40.0001        .00001   40.03
//     ... note that we're careful not to use any "perfect numbers" to avoid accidentally
//         building degeneracies into the mesh

3. Starting Mesh Dimensions (# of nodes in each dimension, inclusive):
   # verts in X    # verts in Y     # verts in Z
       8               8              4
//                       ....try to keep these "background grid" dimensions
//                           small, so that you get good multigrid coarsening ratios...

4. Maximum Hex Cell Aspect Ratio ( Isotropic = 1):
     1
//                      ....flowCart has limited support for anisotropic cell division.

5. Minimum Number of cell refinements on body surface (auto = -1):
    -1

6. Maximum Number of cell refinements:
     7
//                     ...this is the number of refinement sweeps that "cubes" will perform

7. Num of bits of resolution assigned to integer coordinates (maximum = 21):
    21
//                     ...dont mess with this unless you really know what you're doing

** NOTES:
  o   add comments after the ":" terminating each entry but before next line.
       Additional (blank) lines may be added with out messing up the parsing.
  o   User entries in this example are shown in Black, comments in pink and
        fixed text in green. (Actually the parser just checks the input number and the colen ":".)

  #1: A  wetted surface triangulation  with no internal geometry: (usually output from "intersect")
  #4: max difference in number of refinements of 2 directions. cell AR=2^N
  #7: Leave this at "21".
