LinkedCell_Controller is now an Observer.

  • new function updateModelsForNewBoxMatrix() which updates the models in all active views.
  • so far we are hampered by const LinkedCell_Model& ref.
  • Property mode set to 100644

33 * The Controller contains multiple models (i.e. LinkedCell instances) and he
34 * takes care that the view (the interface) can give its functionality with
35 * low computational complexity.
36 *
37 * Here, it contains multiple LinkedCell models, each with different edge
38 * lengths of the inherent mesh. You request a LinkedCell instance from the
39 * controller, but you basically just receive a const interface reference
40 * to a present LinkedCell instance.
