How do you open a second console? I have multiple streams of info I want printed.

I came up with an alternative solution.  Having a command line 
option to show the second stream:

	while(true) {
		auto line = readln();

		if (line) {
			if (line == "quit")
				return;
			else if (line == "dbg matrix")
				yoda.setShowMatrix(true);
			else if (line == "stop dbg")
				yoda.setShowMatrix(false);
			else if (line == "restart")
				yoda.start();
		}
		Thread.sleep(dur!"msecs"(100));
	}
