*DECK NXTLCA
FUNCTION NXTLCA(IPRINT,ITST ,NDIM ,MXMESH,LINMAX,
> MESH ,ORITRK,DIRTRK,DCMESH,
> NBCOR ,NBSINT,ISINT ,TRKLSI)
*
*----------
*
*Purpose:
* To track a Cartesian 2-D or 3-D geometry
* using the NXT tracking procedure.
*
*Copyright:
* Copyright (C) 2005 Ecole Polytechnique de Montreal
* This library is free software; you can redistribute it and/or

* 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
* IPRINT print level.
* ITST type of tracking, where:
* =-1 only the exact geometry
* is considered taking into account the
* submesh in each direction;
* = 0 only the global geometry
* is considered without taking into account the
* submesh in each direction;
* = 1 both the global
* geometry (as a first step) and the exact geometry
* are considered taking into account the
* submesh in each direction.
* NDIM dimension of problem.
* MXMESH maximum number of spatial subdivision in
* $X$, $Y$ or $Z$.
* LINMAX maximum number of segments in a track.
* MESH effective number of spatial subdivision in
* each direction ($X$, $Y$ and $Z$).
* ORITRK a point on the track (origin).
* DIRTRK the track direction (director cosines).
* DCMESH spatial description of the parallepiped.
*
*Parameters: output
* NXTLCA number of surfaces intersected.
* NBCOR number of corner found for each external faces.
* NBSINT number of surface crossed by track.
* ISINT direction of plane intersected and
* the surfaces crossed by the track.
* TRKLSI the surface intersection distance.
