 		@defgroup graphs Graph Structures
 		@ingroup datas
 		\brief Graph structures implemented in LEMON.
 		The implementation of combinatorial algorithms heavily relies on
 		efficient graph implementations. LEMON offers data structures which are
 		planned to be easily used in an experimental phase of implementation studies,
 		and thereafter the program code can be made efficient by small modifications.
 		The most efficient implementation of diverse applications require the
 		usage of different physical graph implementations. These differences
 		appear in the size of graph we require to handle, memory or time usage
 		limitations or in the set of operations through which the graph can be
 		accessed.  LEMON provides several physical graph structures to meet
 		the diverging requirements of the possible users.  In order to save on
 		running time or on memory usage, some structures may fail to provide
 		some graph features like arc/edge or node deletion.
 		You are free to use the graph structure that fit your requirements
 		the best, most graph algorithms and auxiliary data structures can be used
 		with any graph structure.

 		This group describes the map structures implemented in LEMON.
 		LEMON provides several special purpose maps and map adaptors that e.g. combine
 		new maps from existing ones.

 		*/
 		/**
 		@defgroup graph_maps Graph Maps
 		@ingroup maps
 		\brief Special graph-related maps.
 		This group describes maps that are specifically designed to assign
 		values to the nodes and arcs of graphs.
 		*/
 		/**
 		\defgroup map_adaptors Map Adaptors
 		\ingroup maps
 		\brief Tools to create new maps from existing ones
 		This group describes map adaptors that are used to create "implicit"
 		maps from other maps.
 		Most of them are \ref lemon::concepts::ReadMap "read-only maps".
 		They can make arithmetic and logical operations between one or two maps
 		(negation, shifting, addition, multiplication, logical 'and', 'or',
 		'not' etc.) or e.g. convert a map to another one of different Value type.
 		The typical usage of this classes is passing implicit maps to
 		algorithms.  If a function type algorithm is called then the function
 		type map adaptors can be used comfortable. For example let's see the
 		usage of map adaptors with the \c graphToEps() function.
 		\code
 		  Color nodeColor(int deg) {
 		    if (deg >= 2) {
 		      return Color(0.5, 0.0, 0.5);
 		    } else if (deg == 1) {
 		      return Color(1.0, 0.5, 1.0);
 		    } else {
 		      return Color(0.0, 0.0, 0.0);
+		    }
+		  }
 		  Digraph::NodeMap<int> degree_map(graph);
 		  graphToEps(graph, "graph.eps")
 		    .coords(coords).scaleToA4().undirected()
 		    .nodeColors(composeMap(functorToMap(nodeColor), degree_map))
 		    .run();
 		\endcode
 		The \c functorToMap() function makes an \c int to \c Color map from the
 		\c nodeColor() function. The \c composeMap() compose the \c degree_map
 		and the previously created map. The composed map is a proper function to
 		get the color of each node.
 		The usage with class type algorithms is little bit harder. In this
 		case the function type map adaptors can not be used, because the
 		function map adaptors give back temporary objects.
 		\code
 		  Digraph graph;
 		  typedef Digraph::ArcMap<double> DoubleArcMap;
 		  DoubleArcMap length(graph);
 		  DoubleArcMap speed(graph);
 		  typedef DivMap<DoubleArcMap, DoubleArcMap> TimeMap;
 		  TimeMap time(length, speed);
 		  Dijkstra<Digraph, TimeMap> dijkstra(graph, time);
 		  dijkstra.run(source, target);
 		\endcode
 		We have a length map and a maximum speed map on the arcs of a digraph.
 		The minimum time to pass the arc can be calculated as the division of
 		the two maps which can be done implicitly with the \c DivMap template
 		class. We use the implicit minimum time map as the length map of the
 		\c Dijkstra algorithm.

 		\page lgf-format LEMON Graph Format (LGF)
 		The \e LGF is a <em>column oriented</em>
 		file format for storing graphs and associated data like
 		node and edge maps.
 		Each line with \c '#' first non-whitespace
 		character is considered as a comment line.
 		Otherwise the file consists of sections starting with
 		a header line. The header lines starts with an \c '@' character followed by the
 		type of section. The standard section types are \c \@nodes, \c
 		\@arcs and \c \@edges
 		and \@attributes. Each header line may also have an optional
 		\e name, which can be use to distinguish the sections of the same
 		type.
 		The standard sections are column oriented, each line consists of
 		<em>token</em>s separated by whitespaces. A token can be \e plain or
 		\e quoted. A plain token is just a sequence of non-whitespace characters,
 		while a quoted token is a
 		character sequence surrounded by double quotes, and it can also
 		contain whitespaces and escape sequences.
 		The \c \@nodes section describes a set of nodes and associated
 		maps. The first is a header line, its columns are the names of the
 		maps appearing in the following lines.
 		One of the maps must be called \c
 		"label", which plays special role in the file.
 		The following
 		non-empty lines until the next section describes nodes of the
 		graph. Each line contains the values of the node maps
 		associated to the current node.
 		\code
 		 @nodes
 		 label  coordinates  size    title
 (10,20)      10      "First node"
 (80,80)      8       "Second node"
 (40,10)      10      "Third node"
 		\endcode
 		The \c \@arcs section is very similar to the \c \@nodes section, it
 		again starts with a header line describing the names of the maps, but
 		the \c "label" map is not obligatory here. The following lines
 		describe the arcs. The first two tokens of each line are the source
 		and the target node of the arc, respectively, then come the map
 		values. The source and target tokens must be node labels.
 		\code
 		 @arcs
 		         capacity
 2   16
 3   12
 3   18
 		\endcode
 		If there is no map in the \c \@arcs section at all, then it must be
 		indicated by a sole '-' sign in the first line.
 		\code
 		 @arcs
+		         -
 2
 3
 3
 		\endcode
 		The \c \@edges is just a synonym of \c \@arcs. The \@arcs section can
 		also store the edge set of an undirected graph. In such case there is
 		a conventional method for store arc maps in the file, if two columns
 		have the same caption with \c '+' and \c '-' prefix, then these columns
 		can be regarded as the values of an arc map.
 		The \c \@attributes section contains key-value pairs, each line
 		consists of two tokens, an attribute name, and then an attribute
 		value. The value of the attribute could be also a label value of a
 		node or an edge, or even an edge label prefixed with \c '+' or \c '-',
 		which regards to the forward or backward directed arc of the
 		corresponding edge.
 		\code
 		 @attributes
 		 source 1
 		 target 3
 		 caption "LEMON test digraph"
 		\endcode
 		The \e LGF can contain extra sections, but there is no restriction on
 		the format of such sections.
