docs: Assign the |StateSequence| or |LogSequence| object values available
          for the current simulation start point to the current |HydPy| instance.
  
          When the simulation start point is identical with the initialisation
          time point and you did not save conditions for it beforehand, the
          "original" initial conditions are used (normally those of the
          conditions files of the respective *HydPy*  project).
