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

Do not use additional margin/edge for HFT volumes. I assume that to some extent the projected track error should prevent losses of hits in active volumes. This change was not tested properly. I don't know how it may affect track reconstruction with SVT
StiDetectorContainer: Removed method that is not used or defined anywhere
Sti/*: Style and cleanup changes
Sti/StiKalmanTrackFinder.cxx: Doxygen
