Detailed Description

The DtFederateCounterProcessor class consists of filters for FederateCounter messages for forwarder nodes.

The FederateCounter algorithm allows forwarder nodes or the rtiexec to obtain a count of all federates downstream from a given node (including federates directly attached to the specified node). Ie - the rtiexec could obtain a complete federate count by querying the node to which it is directly attached.

Basic Algo:

Initiator sends FederateCountRequest(ID)
Node(ID) receives FederateCountRequest(ID) (and does not forward downstream)
Node(ID) sends FederateCountRequest(DownstreamID) to all downstream connections
Node(ID) aggregates all downstream responses into FederateCountResponse(ID)
All Nodes(X) != Node(ID) simply aggregate downstream responses
