• reduced storage impact of mscw_energy branch (mostly due to change of doubles to floats; removal of unused variables); reduction is on storage requirements is ~25%.
• efficiency improvement in running mscw_energy -> 20% faster
• fine-tuning of docker build scripts to improve build efficiency
• add code to redo stereo reconstruction to CData.cpp. Functions are named reconstruct_3tel_images*
• generalized calculation of MSCW, MSCL, MWR, MWL variables in new classes VMeanScaledVariables
• allow to recalculate dispBDTDirection and dispBDTEnergy in VDispAnalyzer from values per image
• several important improvements and bug fixes in stereo reconstruction code in VTableLookupDataHandler:
  • Chi2 from direction reconstruction not correctly filled from showerpars trees
  • bug fix in setting of NImages and selected telescopes for 3-telescope runs (function fill_selected_images_before_redo_stereo_reconstruction)
• clarified that Erec is from dispBDTEnergy while ErecS is from simple lookup table reconstruction. Change default values for EnergyReconstructionMethod to Erec (method ID 0) for anasum and effective area code.
• introduced consistent naming of tree reader support classes. Moved them from .C to .cpp. Removed obsolete code in these files.
• removed Version from CData class initialize (as it is read from tree doc string).
• removal of CEffFit.h classes (not used anywhere)
• bug fix in SizeSecondMax calculation for 3-tel reconstruction using in mscw_energy the rec_id option (no image selection was applied)
• maintenance and cleanup of obsolete files (see PR #294)
