new module:caplin/core/scheduler/ThreadVisualizer()
ThreadVisualizer allows the scheduling information generated by module:caplin/core/scheduler.ThreadScheduler
to be visualised as a graphical time-line.
This singleton object does not need to be interacted with programmatically. Developers wishing to view threading information can do so by pressing Alt-X (to view a graphical time-line) and Alt-Shift-X (to view a key of anonymous timers and intervals).
