 A simple tool for visualising OSPF network topology as seen by BIRD

+Birdvisu is a library and a graphical app to visualize routing topologies of
+OSPF. It does not implement OSPF on its own, but rather exports current state
+from [BIRD](https://bird.network.cz/) – that's where the name comes from.
+
+The main use case is comparing a reference topology (e.g. a known good one) to
+the current state. This allows Birdvisu to show failed links and other
+anomailes in the network.

+Also, this is the project for my Bachelor thesis.
