Class Description

 Default constructor

 Default constructor specifying minimum and maximum radius

 Default constructor specifying minimum and maximum radius

 Default constructor specifying minimum and maximum radius
 param[0] = dz
 param[1] = Rmin1
 param[2] = Rmax1
 param[3] = Rmin2
 param[4] = Rmax2

 destructor

 compute bounding box of the sphere

 test if point is inside this cone

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

 compute distance from inside point to surface of the cone

 compute distance from outside point to surface of the tube
 compute distance to Z planes

 Static method to compute distance to a conical surface with :
 - r1, z1 - radius and Z position of lower base
 - r2, z2 - radius and Z position of upper base

 compute distance from outside point to surface of the tube

 compute closest distance from point px,py to each corner

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

--- Divide this cone 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 Z 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

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

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

 print shape parameters

 computes next intersection point of curve c with this shape

 paint this shape according to option

 paint this shape according to option

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

 create cone mesh points

 create cone mesh points

 fill size of this 3-D object
