Merge pull request #76 in VECTO/vecto-sim from ~EMQUARIMA/vecto-sim:feature/VECTO-121-driver-strategy-allow-overspeed to develop

* commit '96532a45': (23 commits)
  adapt testcases in vecto 2 and vecto 3 to match each other
  bugfix/workaround geherating plots: -1 is interpreted as 'invalid value' - filter out all -1 values...
  comandline utility to generate graphs
  more tests for overspeed (truck & coach), comparison with vecto 2.2
  adapt driving strategy tests
  handle overload response when braking (i.e. vehicle already decelerates more than intended
  attach units to constants (comparison)
  driverActionBrake: only adapt deceleration if already braking with max. deceleration
  graphwriter: plot acceleration
  SI Class comparison: tolerance has to have same SI unit
  bugfix brakes: brake torque is always positive!
  consistent naming of driverstrategytests
  output of modal results
  output format gradient
  fixed version of shift strategy
  writing graphs for overspeed tests
  correct testdata truck to match vetco 2.2
  attempt to improve overspeed driving behavior
  logging in combustionEngine
  bugfix in searchBrakingPower
