C     --*** GENSHL *** (GENSHL) GENESIS 2D to 3D Shell Program
C     --
C     --GENSHL inputs a 2D GENESIS database and outputs a 3D GENESIS database.
C     --
C     --Expected input:
C     --   o The commands on the standard input device.
C     --   o The 2D GENESIS database on unit 9
C     --     (must have 4 nodes per element,
C     --     cannot have more than 2048 element blocks).
C     --
C     --Output:
C     --   o A listing of the input database information and any errors
C     --     found on the standard output device.
C     --   o The 3D GENESIS Shell database on unit 10.
