This is a variant of the earlier SCALE_GRID that uses the XYZQ_IO package
in place of the CFD_IO_PACKAGE.  It is restricted to 3-space multiblock
grids, and automatically determines whether the input grid is formatted
or not.  The output format must still be prompted for.

ADJUST_GRID applies one or more transformations (shift, scale, rotate,
etc.) to all blocks of the indicated grid, in PLOT3D form:

This version also includes some menu choices that affect only specified
blocks.
