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.

LargeValue is used for internal computations, it is 'long long'
if the length type is integer, otherwise it is 'double'.
- Add named template parameters for LargeValue and Path types.
- Improve numerical stability: remove divisions from the internal
computations. If the arc lengths are integers, then all used
values are integers (except for the cycleMean() query function,
of course).

Rework and fix the implementation of MinMeanCycle (#179)

- Fix the handling of the cycle means.
- Many implementation improvements:
- More efficient data storage for the strongly connected
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.

Simplify the interface of MinMeanCycle (#179)
Remove init() and reset(), and move their content into findMinMean().

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.
