Class Description

 TGeoTube - cylindrical tube class. It takes 3 parameters :
            inner radius, outer radius and half-length dz.

_____________________________________________________________________________
 TGeoTubeSeg - a phi segment of a tube. Has 5 parameters :
            - the same 3 as a tube;
            - first phi limit (in degrees)
            - second phi limit

_____________________________________________________________________________
 TGeoCtub - a tube segment cut with 2 planes. Has 11 parameters :
            - the same 5 as a tube segment;
            - x, y, z components of the normal to the -dZ cut plane in
              point (0, 0, -dZ);
            - x, y, z components of the normal to the +dZ cut plane in
              point (0, 0, dZ);

 default ctor

 ctor

 ctor

 ctor with parameters

 dtor

 compute minimum bounding box of the ctub

 Compute normal to closest surface from POINT.

 check if point is contained in the cut tube
 check the lower cut plane

 Get range of shape for a given axis.

 compute real Z coordinate of a point belonging to either lower or
 higher caps (z should be either +fDz or -fDz)

 compute distance from outside point to surface of the cut tube

 compute distance from inside point to surface of the cut tube

 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.

 set dimensions of a cut tube

 create sphere mesh points

 create sphere mesh points

 Return number of vertices of the mesh representation
