- Implemented using SimpleDiskTracker

- Renamed the vertex and tracker barrel detectors
- Commented out endcap tracker
- Added more detailed to space frame construction.

 - Broke TRD into to planes (per the ref. detector image).

	modified:   compact/vertex_tracker.xml

Fixed ce_GEM overlap

 - CylinderTrackerBarrel_geo can be used to define detailed modules
 which are then placed in barrel array.
 - The modules are cylindrical segments of a tube.

 - Uses the TrapEndcapTracker geometry construction
 - Material thicknesses needs attention.

 - Vertex tracker endcaps are simple disk trackers.

 - Currently just a volume  containing air.

 - Added some fudging numbers for ecal endcap z positions. Should fix
 this in the future..

 - The endcap and barrels were added.
