new client examples

[Steve Vinoski]

Hi Marnie, today you added the client/example directory, but I'm a  
little puzzled by it, because I don't know what it's intended for.  
One issue is that it's not part of the main build, so it will not  
appear as part of any distribution. Another issue is that I don't  
think it should be part of the main build -- only the sources and the  
tests should be.

I'd therefore like to suggest that any samples/examples/demos be put  
under the distribution directory, so they can be included in qpid  
distributions, as I assume we want them to be, without requiring them  
to be part of the main build. I'd be happy to move them if you like.
