CFD Utilities Files

This adaptation of ADJUST_GRID offers just the transformations that would
affect the velocity components of a flow solution containing the state
variables, and applies them to both the flow data and the corresponding
grid.  Both input files should be either cell-centered or vertex-centered,
in PLOT3D format.

For convenience, the options to shift x, y, or z are retained.

   10/03/18    "      "    Added the scaling options that were strangely
                           omitted initially.
   11/28/18    "      "    The scale factors were reverting to defaults after
                           block 1.
   09/27/23    "     "     Switched to the newly-available option in
                           xyzq_io to store function data in Plot3D order
                           in order to make the I/O much more efficient.

For DPLR users, here are the state variables to extract with POSTFLOW
in order to flip Alpha > 0 solutions to Alpha < 0 (say) by scaling Z/w and Y/v
by -1.

Laminar:         0 1000 150 151 152 120 [125]
Baldwin-Lomax:   0 1000 150 151 152 120 [125] 90
