Various improvements in NetworkSimplex.
- Faster variant of "Altering Candidate List" pivot rule using make_heap
instead of partial_sort.
- Doc improvements.
- Removing unecessary inline keywords.

Improve tree update procedure in NetworkSimplex
The new method updates a smaller subtree (fixing a bug) and shifting the
potentials with a costant value.

kpeter [Wed, 15 Oct 2008 12:04:11 +0000] rev 2625
Major improvement in the cost scaling algorithm
- Add a new variant that use the partial augment-relabel method.
- Use this method instead of push-relabel by default.
- Use the "Early Termination" heuristic instead of "Price Refinement".
Using the new method and heuristic the algorithm proved to be
2-2.5 times faster on all input files.

Bug fixes is HaoOrlin and MinCostArborescence
MinCostArborescence
- proper deallocation
HaoOrlin
- the target needn't to be the last in its bucket
- proper size of container (if each node starts in different buckets initially)

Doc improvements
kpeter [Sun, 05 Oct 2008 13:36:43 +0000] rev 2619
Improve network simplex algorithm
- Remove "Limited Search" and "Combined" pivot rules.
- Add a new pivot rule "Altering Candidate List".
- Make the edge selection faster in every pivot rule.
- Set the default rule to "Block Search".
- Doc improvements.
The algorithm became about 15-35 percent faster on various input files.
"Block Search" pivot rule proved to be by far the fastest on all inputs.
