18// TTRAP //
19// //
20// TRAP is a general trapezoid, i.e. one for which the faces perpendicular//
21// to z are trapezia and their centres are not the same x, y. It has 11 //
22// parameters: the half length in z, the polar angles from the centre of //
23// the face at low z to that at high z, H1 the half length in y at low z, //
24// LB1 the half length in x at low z and y low edge, LB2 the half length //
25// in x at low z and y high edge, TH1 the angle w.r.t. the y axis from the//
26// centre of low y edge to the centre of the high y edge, and H2, LB2, //
27// LH2, TH2, the corresponding quantities at high z. //
