Class Description

                                                                        
 TGeoTrap                                                               
                                                                        
 TRAP is a general trapezoid, i.e. one for which the faces perpendicular
 to z are trapezia and their centres are not the same x, y. It has 11   
 parameters: the half length in z, the polar angles from the centre of  
 the face at low z to that at high z, H1 the half length in y at low z, 
 LB1 the half length in x at low z and y low edge, LB2 the half length  
 in x at low z and y high edge, TH1 the angle w.r.t. the y axis from the
 centre of low y edge to the centre of the high y edge, and H2, LB2,    
 LH2, TH2, the corresponding quantities at high z.

 dummy ctor

 constructor. Have to work on it !!!!

 destructor

--- Divide this trapezoid shape belonging to volume "voldiv" into ndiv volumes
 called divname, from start position with the given step. Only Z divisions
 are supported. For Z divisions just return the pointer to the volume to be
 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
