Merge branch 'feat-api-cmds-and-branching'

Implements the programmer-facing API to allow programmatic
specification of a synchronous round. The way in which these put/get
interactions are performed is in an initial shape. Perhaps this will
change in the future.

The second main set of changes is the addion of a 'fork' statement,
which allows explicit forking, and allowing multiple puts/gets over the
same transport link within a single sync round.

#version

import std.reo;

composite main(out c) {
	channel ao -> ai;
	channel bo -> bi;
	channel axo -> axi;
	channel zo -> zi;
	new sync_component(ai, bo);
	new replicator(bi, {axo, c});
	new consensus({axi, zi}, ao);
	new generator(zo);
}

primitive generator(out z) {
	while (true) {
		synchronous (msg x) {
			if (x == null) {
				put(z, x);
				assert !fires(x);
			} else {
				put(z, x);
				assert fires(x);
			}
		}
	}
