Add class FRBHMBasic, which derives FBCM and RADAR. ReferencePoint: Add functions friis_index_for_ap() and friis_indexes_for_ap() (that takes code away from Stock::update_all_friis_indexes()). CartographyAlgorithm and MultilaterationAlgorithm now extend PositioningAlgorithm with "public virtual" instead of "public". CartographyAlgorithm: select_point() must now return a ReferencePoint. MultilaterationMethod: Add pure virtual function multilaterate_2d(). MinMax: Add function multilaterate_2d(). MultilaterationAlgorithm: Add function multilaterate_2d() to map MultilaterationMethod::multilaterate_2d(). Makefile: Fix some dependencies.
