Structure Diagram for GEO: Detector Geometry
                 ============================================
 
         An Introduction to the Structure Diagrams is available.
        NB  These links will be broken until the HTML Version of the Code is installed.
 
 
Introduction
------------
 
These routines handle the geometry of the entire detector.  However they pass
requests for the information within an individual PMT to the PMT SU, so
if this is required the PMT SU is called as well.
