Detailed Description

Factory to create curvilinear geometry for parallel world.

Creates cylinders for straight or angled sections that can be used in a parallel world (only!) for curvilinear coordinates. These have logical volumes with nullptr for material, so can therefore only be used in a parallel world.

The length supplied should be the full length desired. The length of the object returned will be this length - 2x length safety.

Common construction. G4VSolid* can't be const as G4LogicalVolume won't take a const solid.

Convenience method to use the angled method above but with the angle evently spit between each face.

Build a straight section of curvilinear geometry, but with angled faces - typically used for a bend section. Note this is straight though. The normal vectors are w.r.t. the chord of the volume to be built.
