: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.
