    Creates a mesh data structure for testing the {tosl_mesh_slice}.  
    
    The object is a convext barrel-like solid with {NS}-fold rotational
    symmetry about the {Z}-axis and mirror symmetry about the {Z=0}
    plane. It has horizontal faces at top and botton which are regular
    {NS}-sided polygons. The wall of the barrel is a grid of {NS*NR}
    faces, with consisting of {NR} rings each with {NS} flat and weakly
    convex faces. Each face is a trapezoid with two horizontal sides and
    two ``meridional'' sides. Each of the latter is subdivided into
    {NB+1} collinear edges by {NB} vertices inserted at equal intervals.
    
    The object spans in {Z} a bit beyond  the range {-Zmax .. +Zmax}. */
