Added missing callbacks to AVMNodeService. This makes things slow.

Browse Source 
Have to do something about that.
Added getPaths call to AVMService.  Retrieves all possible paths to a node.
Need to do timing tests.
I believe, the 6th version of a Pair template class. This one's public and 
perhaps when we have time we could use it in place of all the inner class
implementations.
