[AG-TECH] Consuming webservice from Venue.py within C++

[Thomas D. Uram]

We expose methods based on the explicit needs of the AG toolkit and the 
anticipated requirements of third-party clients.  For example, most of 
the VenueI interface is used by the venue client or venue management 
applications.  VenueClientI, on the other hand, is mostly anticipated. 
If there's a method that you think should be exposed, please do let us know.

Meanwhile, if you want to access venue state through the venue client, 
you can do so with individual calls, like GetUsers, GetVenueURL, 
GetApplications, etc.  What part of the venue state do you need in your 
application?
