Description

Base classes modelling tracking detectors and the entry point to the geometry.

Public interface

Detector model:

Geometry of GeomDet and GeomDetUnit :

TrackingGeometry is the base class for all tracking geometries ( TrackerGeometry , DTGeometry , CSCGeometry , RPCGeometry ).
GlobalTrackingGeometry is a is a single entry point to the geometries of the tracker and muon detectors. Its main purpose is to allow to get an element of the geometry given its DetId , regardless of wich subdetector it belongs. A typical application is to transform to global coordinates the position of a list of simhits or rechits that belong to several different tracking detectors.

Helper classes:

The GlobalTrackingGeometry can be created in two ways:

using globalTrackingGeometry.cfi, that also creates all slave geometries:

       include "Geometry/CommonDetUnit/data/globalTrackingGeometry.cfi"

using bareGlobalTrackingGeometry.cfi, which does not create any of the slave geometries and allows to specify only few of them.
```
       include "Geometry/CommonDetUnit/data/bareGlobalTrackingGeometry.cfi"
      
```

Completed.
