Detailed Description

Prints global coordinates of PXD hits to demonstrate the Pythonized
VXD::GeoCache.
Only SensorInfoBase is Pythonized (not PXD:SensorInfo and SVD::SensorInfo),
so that there is currently no access to specific PXD/SVD sensor features
(like PXD bulk doping or SVD APV25 time constants - such support can be
easily added, if desired, by placing the classes in the corresponding
linkdef.h file.
Complete geometry and sensor matrix information is, however, available
for all sensor types.
