matDecorator	is an optional decorator for the material
level	is the detector building level 0 - pixel barrel only 1 - pixel detector only 2 - full barrel only 3 - full detector (without stereo modules)
matDecorator	is the source for material decoration
protoMaterial	is a flag to steer proto material to be loaded
surfaceLLevel	is the surface building logging level
layerLLevel	is the layer building logging level
volumeLLevel	is the volume building logging level return a unique vector to the tracking geometry
