* commit 'a0b13ffa':
  bugfix in batterySystem::MaxSoC (resulted in confusion (invalid scores) in hybrid strategy), set fuel costs to 0 if ICE is off
  remove unnecessary / erroneous overrides
  fix testcase exempted primary bus
  bugfix torque converter - handle the case the operating point is null
  bugfix dcdc converter: consider efficiency when checking if battery can supply dcdc converter
  update expected vmod file - changed column names, new columsn
  change gearshift test to use ACEA shift lines instead of new EffShift lines
  update expected vmod and vsum file (new/renamed columns)
  removed pif testcases and related file
  xmlvalidator: restore orignial functionality - return null in case no errors occured
  removing testcases for reading PIF - PIF no longer used
  separate completed bus testcases
  shift polygon tests: use previous (ACEA) shiftlines in testcase (not new EffShift lines)
  in case eta for REESS correction cannot be calculated (no charge/discharge situations) set correctable energy to 0
  updating expected .vmod and .vsum files due to new columns or renamed columns

* commit '93ab1617':
  make min-speed for downshift polygon a parameter
  allow reading pev shift parameters from file
  finetuning PEV shift strategy
  refactoring PEV shift strategy: simplify required methods, prohibit eff-gearshift when at max recuperation, prevent gearshift on drive-off (until target speed reached, em-speed above n_P80low, or operating point at full-load)
  implementing first idea of shift polygons for PEV
