Rename a private type in MCF classes (#180)
The new MCF algorithms define a private map type VectorMap,
which could be misleading, since there is an other VectorMap
defined in lemon/bits/vector_map.h. Thus the new type is
is renamed to StaticVectorMap.

Add citations to CycleCanceling (#180, #184)

Entirely rework cycle canceling algorithms (#180)
- Move the cycle canceling algorithms (CycleCanceling, CancelAndTighten)
into one class (CycleCanceling).
- Add a Method parameter to the run() function to be able to select
the used cycle canceling method.
- Use the new interface similarly to NetworkSimplex.
- Rework the implementations using an efficient internal structure
for handling the residual network.
This improvement made the codes much faster.
- Handle GEQ supply type (LEQ is not supported).
- Handle infinite upper bounds.
- Handle negative costs (for arcs of finite upper bound).
- Extend the documentation.

Small doc improvements + unifications in MCF classes (#180)
Peter Kovacs <kpeter@inf.elte.hu> [Thu, 12 Nov 2009 23:45:15 +0100] rev 877
Small implementation improvements in MCF algorithms (#180)
- Handle max() as infinite value (not only infinity()).
- Better GEQ handling in CapacityScaling.
- Skip the unnecessary saturating operations in the first phase in
CapacityScaling.
- Use vector<char> instead of vector<bool> and vector<int> if it is
possible and it proved to be usually faster.

- The scaling factor can be given for CapacityScaling.

Peter Kovacs <kpeter@inf.elte.hu> [Thu, 12 Nov 2009 23:26:13 +0100] rev 872
Entirely rework CapacityScaling (#180)
- Use the new interface similarly to NetworkSimplex.
- Rework the implementation using an efficient internal structure
for handling the residual network. This improvement made the
code much faster (up to 2-5 times faster on large graphs).
- Handle GEQ supply type (LEQ is not supported).
- Handle negative costs for arcs of finite capacity.
(Note that this algorithm cannot handle arcs of negative cost
and infinite upper bound, thus it returns UNBOUNDED if such
an arc exists.)
- Extend the documentation.
