	  src/libavoid/connector.cpp, src/libavoid/connector.h,
	  src/libavoid/visibility.cpp:

	Add some code to allow querying of items and connectors to find
	out what is attached to them.  This will allow graph layout
	algorithms (currently being work on by Tim Dwyer) to determine 
	a graph structure from the diagram.
