  Feature

• What is the current behavior?
  Topology view are not implemented.

• What is the expected behavior?
  Topology view (bus/breaker view and bus view) have to be implemented. For performance reason calculated buses have to be stored in the DB so that when running a load flow we only have to load calculated buses and not restart from full topology (lot of switches).

• What is the motivation / use case for changing the behavior?
