Fix critical bug in preflow (#372)

The wrong transition between the bound decrease and highest active
heuristics caused the bug. The last node chosen in bound decrease mode
is used in the first iteration in highest active mode.

The original bibartite_matching.eps is kept for future use.

Rename min mean cycle classes and their members (#179)
with respect to the possible introduction of min ratio
cycle algorithms in the future.

The renamed classes:
- Karp --> KarpMmc
- HartmannOrlin --> HartmannOrlinMmc
- Howard --> HowardMmc

The renamed members:
- cycleLength() --> cycleCost()
- cycleArcNum() --> cycleSize()
- findMinMean() --> findCycleMean()
- Value --> Cost
- LargeValue --> LargeCost
- SetLargeValue --> SetLargeCost

Fix gcc 3.3 compilation error (#354)

Rename heap structures (#301)

- KaryHeap --> DHeap
- FouraryHeap --> QuadHeap
- BinomHeap --> BinomialHeap

Add a fullInit() function to Suurballe (#181, #323)
to provide faster handling of multiple targets.
A start() function is also added, just for the sake of
convenience.

Rework and improve Suurballe (#323)

- Improve the implementation: use a specific, faster variant of
residual Dijkstra for the first search.
- Some reorganizatiopn to make the code simpler.
- Small doc improvements.
