Removed references to sections and dependencies, instead there are just childrenTasks. Checking user errors regarding blocking tasks with flush/display rules, and pushing a blocking child after a parent has been pushed without know that it has a blocking child. Making sure that flushed tasks have a parent in displayTargets otherwise it should listen to all tasks' afterDisplay events to check for a stub. Fixed Task.toString method, which was not embeding children when js is disabled.
