Strange Visualization Behavior

[ThomasThelen]

When showing the graphs for solve_bfs and solve_bidirect_dfs, strange behavior is encountered. This is probably either a problem with the solution path or with the visualization code. This can be seen in early versions, and also current versions.

I know the visualization and the algorithms here are not optimally implemented yet so I expect there to be some strange behaviours as you mention. The depth-first one is the only properly tested and that one should work as expected I think. As mentioned in other issues comments, I unfortunately won't be spending much time this spring trying to fix this stuff as I have to focus on my masters project.
