Motivation
Writing a ML2 task with relatively complex timing dependency.

Adapter Chain
child = Adapter1(tracker);
parent = Adapter2(child);
topmost = Adapter3(parent);
scene = create_scene(topmost);
run_scene(scene);
This programming paradigm is really similar to that used in Tensorflow. The Adapters are like operator function on variables. But nothing really happen to the scene until run_scene
The chain start with a special kind of adapter called tracer: eye_, eye2**, **joy, joy2**, **touch, button_, mouse_ and null_
Note Create scene can take a second argument, index to the task objects
fix = SingleTarget(eye_);
fix.Target = 1; % TaskObject#1
fix.Threshold = 3; % 3 deg
wth = WaitThenHold(fix);
wth.WaitTime = 5000;
wth.HoldTime = 500;
scene = create_scene(wth, [1 2]); % TaskObject#1 & #2
run_scene(scene);
Besides, run_scene could be run with a 2nd argument, eventcodes which will be sent out when 1st scene finished.
run_scene(scene, eventcodes);
Note, the trackers are predefined in timing file eye_, eye2**, **joy, joy2**, **touch, button_, mouse_ and null_ . Thus we don’t have to redefine it separately.
For manual of common adapters, see doc.
Playing Movie
Note Original Movie object doesn’t provide functionality to change the size of presentation. But we can use general purpose resizing object function to achieve that.
