Detailed Description

The main demo logic for executing le::ghs::GhsState across a network

A configurable multi-agent/multi-process executable built on nng that uses le::ghs::GhsState

do_main()

int demo::GhsDemoExec::do_main	(	int	argc,
		char **	argv
	)

A single entry point function that should be called from main()

The main loop consists of:

1. Reading demo::Config information about the peers and their tcp endpoints from an ini file and from stdin
2. Initializing all the nng sockets inside a demo::Comms object from that config
3. Using Comms::little_iperf() and Comms::exchange_iperf() to create link metrics
4. Populating a le::ghs::GhsState object from the Config object and link information gathered by demo::Comms
5. Calling le::ghs::GhsState::start_round() to get the first set of messages, and feeding those into Comms
6. Spinning on Comms::has_msg() and calling Comms::get_next() to retrieve a message, then pushing that message payload into le::ghs::GhsState::process() to get the next set of message to send
7. Continuing that process until le::ghs::GhsState::is_converged() returns true
8. Printing stuff

If you want to replicate this, study this loop, and pay close attention to how little_iperf() does its work and especially sym_metric().
