Detailed Description
A base class for magnetic fields in local to be used in global coordinates.
This base class provides the aggregate inheritance and utility functions for magnetic fields in local coordinates to be used in global coordinates.
Constness is particularly important here as member functions are called from inside G4MagneticField::GetField function which is const.
This owns the field it wraps.

Apply the global to local transform, query the wrapped field object and transform this field to global coordinates before returning.

As we use a discrete member field object, we do not need to apply the transform. Override default method and just directly call GetField().
