363	Implementing a planar graph type	gyorokp	Balazs Dezso	My goal is to implement classes for planar graphs. The !PlanarGraph class maintains a topology of nodes, edges and faces and provides algorithms that are characteristic to planar graphs. !PlaneGraph extends this functionality with geometric properties, such as node coordinates and arc shapes.	enhancement	new	major	LEMON 1.3 release	core	hg main
