introduce lookahead interface

minimal dirvingcycle test - modal results output, refactoring si units output, interface for vehicle distance

fix engine-only simulation runs / time-based run

Merge branch 'feature/VECTO-70-wheels-engine-only-driving-cycle' of https://webgate.ec.europa.eu/CITnet/stash/scm/~emquarima/vecto-sim into feature/VECTO-109-include-latest-changes-in-geabox-engine

MAJOR REFACTORING: change signature of Connector Interfaces from TimeSpan to Second. Remove TimeSpan completely (lack of precision)

butfix in equation

refactoring VectoSimulationComponent: split writing modal data and committing state into separate methods

Merge pull request #58 in VECTO/vecto-sim from ~EMQUARIMA/vecto-sim:feature/VECTO-105-SimulationDataFactory to develop

* commit '36157b56': (48 commits)
  testcases work
  merge attempt 2
  merge
  refactoring reading input files - separate dataObjectAdapter
  implemented access to whtc correction
  tests for whtc correction
  computing shift polygons (declaration mode) woks
  more work on creating powertrain in declaration mode, generic shifting polygons, necessary functionality in fullLoadCurve
  adjustments for new declaration files (and formats)
  corrected minor error in AssertHelper
  code formatting: replace spaces by tabs
  code refactorings: optimize imports, qualify by type name, added AssertHelper
  implemented steering pump auxiliaries in declaration mode, renamed declaration classes (removed declaration from name, because it is already in namespace)
  aux steering pump
  implemented pneumatic system aux. updated ps-table values to watt
  construction of powertrain works for engineering and engine-only mode
  implemented hvac aux
  wrote test for hvac
  corrected calculation of electrical systems aux
  implemented fan aux in declaration mode
  ...

- renaming SI.Double to SI.Value (former .Value is now .Clone)
- adding IsEqual methods to SI class

filtering drivingCycle Data for 'redundant' entries
computing altitude over distance-based cycle
introduce initialize method in port interfaces
