// A G4Parallepiped, essentially a box with half lengths dx,dy,dz `skewed'
|
|
// so that there are angles theta & phi of the polar line joining the faces at

// +-dz in z, and alpha formed by the y axis and the plane joinng the

// centre of the faces G4Parallel to the z-x plane at -dy and +dy.

// A G4Para is defined by:

// alpha Angle formed by the y axis and by the plane joining

// the centre of the faces G4Parallel to the z-x plane
