20 // PARA is parallelepiped. It has 6 parameters, the half length in x, //
21 // the half length in y, the half length in z, the angle w.r.t. the y //
22 // axis from the centre of the low y edge to the centre of the high y //
23 // edge, and the theta phi polar angles from the centre of the low //
24 // z face to the centre of the high z face. //
