> MAXMSH,MAXREG,MAXPIN,NBTCLS,ITSYM ,IDFEX ,
> DCMESH,NAGGEO,ITURN ,IDIRR ,NFSUR ,NFREG ,

*
*----------
*
*Purpose:
* Create a multicell description for the geometry and verify
* if intrinsic cell symmetry required by boundary conditions
* are satisfied.
*
*Copyright:
* Copyright (C) 2005 Ecole Polytechnique de Montreal
* This library is free software; you can redistribute it and/or
* modify it under the terms of the GNU Lesser General Public
* License as published by the Free Software Foundation; either
* version 2.1 of the License, or (at your option) any later version.
*
*Author(s):
* G. Marleau.
*
*Parameters: input
* IPGEO pointer to the GEOMETRY data structure.
* IPTRK pointer to the TRACKING data structure.
* IPRINT print level.
* NDIM problem dimensions.
* ILCELL cell level.
* NBOCEL number of cells in original geometry.
* MAXMSH maximum number of elements in MESH array.
* MAXREG maximum number of elements in MIX array.
* MAXPIN maximum number of pins in clusters.
* NBTCLS total number of cluster geometry.
* ITSYM array to identify the symmetry to test for each original
* cell where:
* ITSYM(1,*) identify $X$ symmetry;
* ITSYM(2,*) identify $Y$ symmetry;
* ITSYM(3,*) identify $Z$ symmetry;
* ITSYM(4,*) identify $X-Y$ symmetry.
* A value of 0 indicate that the geometry does not need
* to be verified while a value of 1 implies a verification
* of the geometry.
* IDFEX identify faces associated with external boundary for a
* generating cell and number of times this cell is used. Here:
* IDFEX( 1,*) identify bottom $U$ hexagonal face;
* IDFEX( 2,*) identify top $U$ hexagonal face;
* IDFEX( 3,*) identify bottom $V$ hexagonal face;
* IDFEX( 4,*) identify top $V$ hexagonal face;
* IDFEX( 5,*) identify bottom $Z$ face;
* IDFEX( 6,*) identify top $Z$ face;
* IDFEX( 7,*) not used;
* IDFEX( 8,*) not used;
* IDFEX( 9,*) identify bottom $W$ hexagonal face;
* IDFEX(10,*) identify top $W$ hexagonal face.
* DCMESH global mesh for each cell.
* NAGGEO names of generating geometries.
* ITURN geometry turns.
* IDIRR direction of cell (1 for XYZ, 2 for YZX and 3 for ZXY).
* Note: for CAR3D without pins IDIRR=1
* for CAR3D with pins IDIRR specified by pins direction.
*
*Parameters: output
* NFSUR final number of surfaces.
* NFREG final number of regions.
* MXGSUR maximum number of surfaces for any geometry.
* MXGREG maximum number of region for any geometry.
