StiDetector: Added splitIt method to split this volume along the radial direction. Also added a missing assignment for StiElossCalculator in copy
StiDetectorBuilder: Added parameters defining the volume splitting procedure and a call to the splitting routine based on these parameters
Auto-segmentation of radially oriented volumes (Victor/Dmitri/Gene)
Merge branch 'ds-vsplit'

Process StiMaker attributes to create test volumes
Added new options for Sti test to check overlapping and non-overlapping tubes
In StiMaker construct the PXL detector using the option for ideal/survey geometry transformations. The default is to use a non-ideal survey geometry
StiMaker/StiDetectorVolume.cxx: Style and cleanup changes
Moved MyClear() to beginning of Make() to allow for access of StiTracks by other makers
Use SstDbMaker and SstDetectorBuilder when building SST in StiMaker
Not verified changed! Rotated matrix by 90 degrees
Slighlty improved colors used to draw Sti volumes
