Detailed Description

Class that constructs a Geant4 model of an accelerator.

Mandatory class that must be supplied for a valid Geant4 simulation. As construction is based on user input (via the parser) for a potentially large number of items, the construction process is factorised into key steps with member functions and makes use of factories for components and tunnel segments.

Loop over a beam line and place elements in a container (world). If a sensitive detector is specified in each component, this is applied to each volume. If regions are desired, the element is looked up in the region definitions and that is set up. If registerInfo, physical volume info is created and placed in a pv info registry. Public and static so it can be used by parallel world constructors. Last argument is whether to use the placement transform for curvilinear coordinate geometry that's different in the case of tilted dipoles.
