Doc improvments backported from hg 9df0fe5e5109

Bug fix in heap_test.cc.

Several doc improvements and fixes in maps.h and concepts/maps.h.

Small fixes in README.

Improvements and fixes in dim2.h.

- Several doc improvements.
- Fix BoundingBox::operator& implementation.

Translate Hungarian varible names and improve messages in dim_test.cc.

Fix the rename script.

grid_ugraph.h: fixed #18 (global functions inlined)

Improved rename script to handle includes correctly.

Reveal an existing functionality in the documentation

Cleanup in the minimum cost flow files.
The changes only affects the documentation and the look of the source codes.

Reimplemented MinMeanCycle to be much more efficient.
The new version implements Howard's algorithm instead of Karp's algorithm and
it is at least 10-20 times faster on all the 40-50 random graphs we have tested.

Minor doc fix

Happy New Year to LEMON (+ better update-copyright-header script)

Improved rename script to avoid "undirected digraph".

Include functional because of std::less.

Bug fix

Bug fix

Avoiding warnings

DynEdgeLookUp implementation based on splay trees
In general case it is slower than the static version, but it should not
refreshed on the change of the graph

Bug fix in doc

Using operation traits in dijkstra

Modified rename script (BpGraph instead of Bigraph).

Redesigned CapacityScaling algorithm with almost the same interface.
The new version does not use the ResidualGraphAdaptor for performance reasons.
Scaling can be enabled and disabled with a parameter of the run() function.

Improved docs.

Bug fix in undirected graphs (adding loops)
Bug fix in undirected edgesets (alteration notifying)

Redesigned undirected edgesets (like the smart or ugraph)

Build fix.

setAll for iterable bool maps

Added the function isFinite(), and replaced the calls to finite() with it.
This was necessary because finite() is not a standard function. Neither can
we use its standard counterpart isfinite(), because it was introduced only
in C99, and therefore it is not supplied by all C++ implementations.

Makefile fix.

Bad documentation

Adding doc

Documentation for lemon tools
