Detailed Description

A definition of the envelope that contains the tracker sensitive detectors. The information is not automatically computed from the Tracker geometry, but is hard-coded in this class. However, there is very little freedom to modify the tracker size (ECAL constraint...), so a fast access to this information is very useful. The recommended use is: Inside the TrackerBounds tracker propagators are expected to work accurately. Outside of this volume use some kind of geane.
