Pull request #87: Feature/VECTO-1441 remove oscillating behavior for pcc with hybrids and battery electric vehicles

Merge in VECTO/vecto-dev from VECTO/mk_vecto-dev:feature/VECTO-1441-remove-oscillating-behavior-for-pcc-with-hybrids-and-battery-electric-vehicles to develop

* commit '9102a967': (129 commits)
  removed P1 Bus Hybrid Roeck Testcases
  reverted Delaunay Map again to previous implementation
  replaced all [Test] attributes by [TestCase]
  added delta for double comparisons in test cases
  added missing files for tests
  reverted Sum Method back to previous behavior (returning Null if the source was empty)
  replace all [TestCase] attributes by [Test] (has different visualisation in testrunner)
  Moved CyclesCache to DeclarationData
  DefaultDriverStrategy CoastingForce: uses correct engine and the correct internalvoltage from the battery, adds up drag from combustion and electric
  corrected error with AddRuns returning integers now
  BusAuxiliaries removed comment
  Alternator: restore previous version (unchanged)
  Removed setting LastAccessTime
  AddRuns returns the RunIdentifiers again (not the run object)
  removed testcase for QuadraticEquationFit - not implemented anymore
  ModalDataContainer ElectricMotorEfficiencyGenerate revert back to old version
  VectoMath removed FitQuadraticEquation
  DriveDistance: renamed variable for debug
  CompletedBusFactorMethodTests cannot be run in parallel (out-of-memory)
  DefaultDriverStrategy: container cannot be null, therefore null-coalescing is not needed.

DefaultDriverStrategy CoastingForce: uses correct engine and the correct internalvoltage from the battery, adds up drag from combustion and electric

added new testcase J for E4; reduced engines to 2 again; updated drag torque curve to a more realistic one
