[Nsi-wg] NSI specific topology recommendation for plug fest.

[Jeroen van der Ham]

Hi,

I've updated the editor again, adding:

- connectedTo for NSAs (note that a top connectedTo blob only connects to a bottom connectedTo blob and vice versa)
- contactInfo for NSAs
- hasSTP to link NSNetworks and STPs (was added yesterday)

Jeroen.
