%Docstring(signature="appended")
:py:class:`QgsNetworkStrategy` defines strategy used for calculation of the edge cost. For example it can
take into account travel distance, amount of time or money. Currently there are two strategies
implemented in the analysis library: :py:class:`QgsNetworkDistanceStrategy` and :py:class:`QgsNetworkSpeedStrategy`.
:py:class:`QgsNetworkStrategy` implemented using "strategy" design pattern.
