Class Description

______________________________________________________________________________

 TUBE is a tube. It has 6 parameters:

     - name       name of the shape
     - title      shape's title
     - material  (see TMaterial)
     - rmin       inside radius
     - rmax       outside radius
     - dz         half length in z
