The class implementing the object is called 'DiffAutoSimArrayObject'. The following functions have
been addded to generate the objects:
self._auto_object_Diso_sim()
self._auto_object_Dpar_sim()
self._auto_object_Dper_sim()
self._auto_object_Dpar_unit_sim()
self._auto_object_Dx_sim()
self._auto_object_Dy_sim()
self._auto_object_Dz_sim()
self._auto_object_Dx_unit_sim()
self._auto_object_Dy_unit_sim()
self._auto_object_Dz_unit_sim()
These are simply copies of the non-simulation functions with the added argument 'i' for selecting
the simulation.
