- open the clutch if the vehicle's speed gets too low and the engine speed goes below idle speed

consider the case that 'nextTargetSpeed != 0' for computing the next simulation distance

  vecto 2.2 job-file for air-drag computation
  additional tests for air-drag power loss; corrected testcase due to chages in air-drag computation
  restructuring code
  refactoring air-drag computation
  tests for AirResistance
  corrected BaseWindSpeed (CrossWind Correction) to 3 m/s
