Graph Class

This .NET class wraps the AcDbGraph ObjectARX class. 

This class provides a generic graph container implementation. One other class is also involved in the graph mechanism: GraphNode. 

Detection for circular references is done by internally creating a duplicate set of references in each node and then trimming away all leaf nodes, which terminate without circularity. If any nodes remain in the duplicate graph, those nodes exist in a cycle. Graph.FindCycles() is used to set up the internal cycle information and enable several query methods to return information about any cycles found.
