Class Description

 Default constructor

 Default constructor specifying minimum and maximum radius

 Default constructor specifying minimum and maximum radius
 param[0] = Rmin
 param[1] = Rmax
 param[2] = dz

 destructor

 compute bounding box of the tube

 test if point is inside this tube

 compute closest distance from point px,py to each corner

 compute distance from inside point to surface of the tube (static)

 compute distance from inside point to surface of the tube

 static method to compute distance from outside point to a tube with given parameters

 compute distance from outside point to surface of the tube and safe distance
 fist localize point w.r.t tube

 computes the distance to next surface of the sphere along a ray
 starting from given point to the given direction.

--- Divide this tube shape belonging to volume "voldiv" into ndiv volumes
 called divname, from start position with the given step. Returns pointer
 to created division cell volume in case of Z divisions. For radial division
 creates all volumes with different shapes and returns pointer to volume that
 was divided. In case a wrong division axis is supplied, returns pointer to
 volume that was divided.

 Divide all range of iaxis in range/step cells

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

 print shape parameters

 paint this shape according to option

 computes next intersection point of curve c with this shape

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

 create tube mesh points

 create tube mesh points

 fill size of this 3-D object
