Ensure strongly polynomial running time for CycleCanceling (#436)
The number of iterations performed by Howard's algorithm is limited.
If the limit is reached, a strongly polynomial implementation,
HartmannOrlinMmc is executed to find a minimum mean cycle.
This iteration limit is typically not reached, thus the combined
method is practically equivalent to Howard's algorithm, while it
also ensures the strongly polynomial time bound.

computations. If the arc lengths are integers, then all used
values are integers (except for the cycleMean() query function,
of course).

components.
- Better handling of BFS queues.
- Merge consecutive BFS searches (perform two BFS searches
instead of three).

This version is about two times faster on average and an order of
magnitude faster if there are a lot of strongly connected components.

Add a warning for List(Di)Graph::Snapshot (#311)
and extend tests for snapshots

Modify the implementation of ListDigraph::ArcIt (#311)

The new implementation is based on out-arc iteration (like
ListGraph::ArcIt) instead of in-arc iteration to make it
consistent with the documentation.

Much better implementation for node splitting (#311)
in ListDigraph. This solution is the same as the one that
is used in SmartDigraph. It is much faster and does not
invalidate any iterator like the former implementation.

Add a resize() function to HypercubeGraph (#311)
just like the similar functions in other static graph structures,
and extend the test files to check these functions.

Add reserve functions to ListGraph and SmartGraph (#311)
ListDigraph and SmartDigraph already have such functions.
