Rewrote typing to use indices.

Currently it is slower than before, because we do a HashMap lookup
followed up by actually using the index. But it serves as the basis
for a faster type inferencer.

The main goal, however, is to fix the manner in which polymorph
types are determined. The typing queue of functions still needs to
correctly write this data to the type table.

#version 100

import std.reo;

composite main(in asend, out arecv, in bsend, out brecv, in csend, out crecv) {
    channel xo -> xi;
    channel yo -> yi;
    channel zo -> zi;
    // Every synchronous round, at most one message is sent (to determine a global order)
    new mymerger(asend, bsend, xo);
    new mymerger(csend, xi, yo);
    // If a message is sent, it is broadcast to every recipient
    new replicator(yi, {arecv, zo});
    new replicator(zi, {brecv, crecv});
}

primitive mymerger(in a, in b, out c) {
    while (true) {
        synchronous {
            if (fires(a) && !fires(b) && fires(c)) {
                put(c, get(a));
            } else if (!fires(a) && fires(b) && fires(c)) {
                put(c, get(b));
            } else {
            	assert !fires(a) && !fires(b) && !fires(c);
            }
