[Nsi-wg] paths, connections, path objects, connection objects

Attached is a document that is very rough that starts to define issues with paths and connections. It needs a lot more work, but does start to put some idea on paper. It may or may not be worth talking about tomorrow. I can try to refine it more for next week with or without input. Sorry it isn't better, but I ran out of time, and it is harder to put on paper than I expected. John
