Merge #301

Also test fullInit() in suurballe_test (#181, #323)

Add traits class + named parameters to Suurballe (#323)

The following types can be modified using named parameters:
- FlowMap
- PotentialMap
- Path
- Heap + HeapCrossRef

Merge #181, #323

Rename heap structures (#301)

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

Merge bugfixes #323 to branch 1.1

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.

Remove unnecessary integer requirement in Suurballe (#323)

Bug fix in Suurballe (#323)

Configurable glpk prefix in ./scripts/bootstrap.sh and ...
unneeded solver backends are explicitely switched off with --without-*

Support tolerance technique for BellmanFord (#51)

A new operation traits class BellmanFordToleranceOperationTraits
is introduced, which uses the tolerance technique in its less()
function. This class can be used with the SetOperationTraits
named template parameter.

Merge #332

ArgParser can throw exception instead of exit(1) (#332)

Better return type for cycleLength() functions (#179)
in the min mean cycle algorithms.

The original Value type is used instead of the LargeValue type,
which is introduced for internal computations.

New heuristics for MCF algorithms (#340)
and some implementation improvements.

- A useful heuristic is added to NetworkSimplex to make the
initial pivots faster.
- A powerful global update heuristic is added to CostScaling
and the implementation is reworked with various improvements.
- Better relabeling in CostScaling to improve numerical stability
and make the code faster.
- A small improvement is made in CapacityScaling for better
delta computation.
- Add notes to the classes about the usage of vector<char> instead
of vector<bool> for efficiency reasons.

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.
