Full realtime sim up and running

[pabogdan]

Built upon your changes and tested that it works using the following script. Closing the simulation works in both in the case that you run sim.run(None) in a new thread and in the case that you have a different thread stopping the simulation.

import thread
import nengo
import numpy as np
import nengo_spinnaker
import time

model = nengo.Network(label="NetworkName")


with model:
    in_A = nengo.Node(output=np.sin)
    A = nengo.Ensemble(50, 1)
    out_A = nengo.Node(size_in=1)

    nengo.Connection(in_A, A)
    nengo.Connection(A, out_A)

sim = nengo_spinnaker.Simulator(model, period=None)


def sim_stop():
    global sim
    time.sleep(20)
    sim.stop()

thread.start_new_thread(sim_stop, ())
with sim:
    print "Sim inc"
    sim.run(None)
    print "Sim closed"

print "Board wiped"
