*DECK NXTBCG
SUBROUTINE NXTBCG(IPGEO ,IPTRK ,IPRINT,NDIM ,ITYPBC,IDIRG ,
> IDIAG ,ISAXIS,IHSYM ,ILEAK ,IPRISM )
*
*----------
*
*Purpose:
* To read boundary conditions and symmetries and verify
* if information is consistent. Also prepare axis for
* symmetry identification.

*
*Author(s):
* G. Marleau.
*
*Parameters: input
* IPGEO pointer to the GEOMETRY data structure.
* IPTRK pointer to the TRACKING data structure in
* update or creation mode.
* IPRINT print level.
* NDIM problem dimensions.
* ITYPBC type of boundary conditions where:
* =0 for geometry with Cartesian
* boundaries;
* =1 for geometry with annular
* boundary;
* =2 for geometry with hexagonal
* boundary;
* IDIRG geometry main direction:
* =1 for $X-Y-Z$ geometry;
* =2 for $Y-Z-X$ geometry;
* =3 for $Z-X-Y$ geometry.
* IPRISM projection axis for prismatic tracking.
*
*Parameters: output
* IDIAG the diagonal symmetry flag where:
* =-1 indicates X- DIAG symmetry;
* = 1 indicates X+ Y- DIAG symmetry;
* = 0 indicates no DIAG symmetry.
* ISAXIS symmetry vector for each direction.
* IHSYM hexagonal symmetry option where:
* = 0 geometry is not hexagonal;
* = 1 for S30;
* = 2 for SA60;
* = 3 for SB60;
* = 4 for S90;
* = 5 for R120;
* = 6 for R180;
* = 7 for SA180;
* = 8 for SB180;
* = 9 for COMPLETE;
* =10 for R60.
* ILEAK leakage option where:
* =1 indicates that there is no out of cell leakage;
* =0 indicates that there no out of cell leakage.
