Switched to PXL sensitive layer geometry with one Sti volume per ladder centered
at z=0. The loop over sensors removed and the indexing of the volumes changed
accordingly. Update from Jonathan Bouchet
Inner loop indentation adjusted
Grompf! Inverted ssd <-> sst now corrected (thx DS)
Remove RnD as old approach
Reduced the number of LOG_DEBUG statements to mitigate possible slowdown due to unnessary conditional checks
Added virtual keyword to methods because that's what they are
Decrease thickness of inactive material tube, and enable sensitive silicon layers
Append includes with explicitly specified sub-directories for easier reference
Added option to StiPixelDetectorBuilder/Group to switch between ideal and DB-based geometries
Added a check to make sure DB transformations exist when user requests a DB-base geometry
Added two more cylindrical volumes from the pixel support tube mother volume (PSTM)
Added some material between the PXL layers
PXL DB dataset has been renamed to avoid conflict with StPxlDbMaker's name
Name truncation leads to issues with unique names
Reduce visibility of inactive materials
Error about missing hit collection => warning
Fixed style with astyle -s3 -p -H -A3 -k3 -O -o -y -Y -f
Uniform improvements in Sti objects output streamers
Remove unused variables
Don't proceed if the DB information is not available
