TStiKalmanTrackNode: Added new data member to keep the node's volume density. These data are saved in the HFT tree
TStiKalmanTrackNode: Use the absolute energy loss value reported by Sti. It is due to a known feature of Sti changing track direction due to incorrect radial ordering
Pass user program options to output histograms

StiScanRootFile: Added data member to access user arguments and options provided in the command line
stiscan: Pass user program options to StiScanRootFile object
Do not calculated axis range automatically. Rely on user's input in program options
Removed semi-automatic axis range adjustment (PrettifyHists()) in favor of manual user options set via command line
StiScanPrgOptions: Added command line options to control the output histogram axis limits
Let histogram containers accept user program options to control histogram axis ranges
StiScanRootFile: Pass user command line options to histogram containers. User can specify new axis ranges
StiScanHistContainer: Set default axis limits to some reasonable values and use them to estimate the number of bins
StiScanHistContainer: Use user provided axis limits (if min < max) instead of defaults
StiScanHistContainer: Do not create profiles because they are useless. Added a projection for selecte volumes profile
instead
Minor style corrections and space adjustments
Removed ClassDef macro from the transient classes
Start TGeo volume loop one level above IDSM. This will allow to naturally consider volumes outside of IDSM
stiscan: Remove TpcRefSys_1/ substring from the TGeo volume path. This allows for easier matching with geant paths which do not have such string by design
