Class Description

 TGeoPara - parallelipeped class. It has 6 parameters :
         dx, dy, dz - half lengths in X, Y, Z
         alpha - angle w.r.t the Y axis from center of low Y edge to
                 center of high Y edge [deg]
         theta, phi - polar and azimuthal angles of the segment between
                 low and high Z surfaces [deg]

 destructor

 compute bounding box

 Compute normal to closest surface from POINT.

 test if point is inside this sphere
 test Z range

 compute distance from inside point to surface of the para

 compute distance from inside point to surface of the para
   Warning("DistFromOutside", "PARA TOIN");
   Double_t snxt=TGeoShape::Big();

--- Divide this paralelipiped shape belonging to volume "voldiv" into ndiv equal volumes
 called divname, from start position with the given step. Returns pointer
 to created division cell volume. In case a wrong division axis is supplied,
 returns pointer to volume to be divided.

 Get range of shape for a given axis.

--- Fill vector param[4] with the bounding cylinder parameters. The order
 is the following : Rmin, Rmax, Phi1, Phi2

 Fills real parameters of a positioned box inside this. Returns 0 if successfull.

 in case shape has some negative parameters, these has to be computed
 in order to fit the mother

 print shape parameters

 computes the closest distance from given point to this shape, according
 to option. The matching point on the shape is stored in spoint.

 create sphere mesh points

 create sphere mesh points

 fill size of this 3-D object
