MACROS for debug map usage

Bug fix

Easier inverse than m.inverse()[a] => m(a)

Better handling of inexact computation.
We do not use tolerance for excess, just for edges

clone => build renaming

Query functions have been implemented for GLPK (CPLEX breaks at the moment, I guess): These functions include:
retrieving one element of the coeff. matrix
retrieving one element of the obj function
lower bd for a variable
upper bound for a variable
lower and upper bounds for a row (these can not be handled separately at the moment)
direction of the optimization (is_max() function)

More sophisticated warning messages.

Fix 'unused variable' warnings

Oops. I did not mean to break the repository.

Some query functions got implemented, but only for GLPK.

Check for gcc version 3.3, 3.4 and 4.0 as well

SimpleMap and SimpleWriteMap
- Trivial adaptors, but they are useful in some case

Some combined maps will be reference map if the first
template parameter map is reference map or not. If I want
to give a refernce map as first map but there is a non
reference map parameter then I should wrap my first map
to a regular read-write map.

Update the Path concept

DirPath renamed to Path
The interface updated to the new lemon interface
Make difference between the empty path and the path from one node
Builder interface have not been changed

Instead of:

graphReader(std::cin, graph).

Bug fix

Using abort() instead of exit(1)

If a program is aborted then the call stack can be analyzed with debugger.

UNDIRGRAPH_TYPEDEFS => UGRAPH_TYPEDEFS

The graph adadptors can be alteration observed.
In most cases it uses the adapted graph alteration notifiers.
Only special case is now the UndirGraphAdaptor, where
we have to proxy the signals from the graph.

The SubBidirGraphAdaptor is removed, because it doest not
gives more feature than the EdgeSubGraphAdaptor<UndirGraphAdaptor<Graph>>.

The ResGraphAdaptor is based on this composition.

Some classes assumed that the GraphMaps should be inherited
from an ObserverBase. These classes parents replaced with
DefaultMap which cause that the graph maps should not be
inherited from the ObserverBase.

Bug fix

ANodeIt/BNodeIt should not be inherited from ANode/BNode

The reason:
assert(graph.id(ANodeIt(graph)) == graph.id((Node)ANodeIt(graph)));

Revising the bpugraph concept

We need a public but very limited ANode and BNode class
It can be used with ItemSetTraits and with some special maps

By example:
DescriptorMap<Graph, ANode>
InvertableMap<Graph, ANode, string>
IterableBoolMap<Graph, ANode>
IterableIntMap<Graph, ANode>
IterableValueMap<Graph, ANode, string>

Bug fix
friend does not declares type

New iterable map with comparable values
it uses linked lists and balanced binary tree

IterableBoolMap has ItemIt type as the other iterable maps

InvertableMap got ValueIterator

Solve bug #23: Floating versus Integer Coordinates

- BoundingBox values rounds to integer
- The generated .eps rescales if the bounding box were too small otherwise.

Better doc.

Use [] instead of set().

Functions added to set the edges/corners of the bounding box directly.

Do not rely on the autodetection of cplex and glpk.

Changes in doc

Documenatation of MapWin.

Documentation of MapSelector. If no default value is present in MapSelector, Reset button does not appear.

Documentation of NoteBookTab. Redundant function parameters are removed from other classes as well.

Documentation of NewMapWin.

Documentation of MainWin.

If default value of a new map is constant, the newly created elements will get that value as well. Documentation is added to BrokenEdge, MapStorage and GraphDisplazCanvas classes.

The tree that is created for evaluation of expression string at new map creation is deleted after usage.

Creation of algorithm dialog is even simpler by the usage of the newly created addMapSelector function.

Forgotten file committed.

In algorithm window maps can be selected and reated through MapSelector widget.

Set arrow coordinates when creating a new edge.

MapSelector has become a standalone class.

Result of KruskalGUIAlgo is refreshed if displayed, but no more setin a forced way.

Reformatting: too long code lines.

Kruskal algorithm can be run from GUI from now on.

Several changes. \n If new map is added to mapstorage it emits signal with the name of the new map. This was important, because from now on not only tha mapwin should be updated. \n Furthermore algobox gets a pointer to mapstorage instead of only the mapnames from it. This is important because without it it would be complicated to pass all of the required maps to algobox.

Set the move tool active by default.

Communication with algorithm window is developed.

Happy new year to LEMON
