Get the list of tasks to execute.
Get the list of tasks to execute.
All tasks, multi-tasks, workflows, and other task-like-entities should implement this method. In the execution graph, the returned tasks are all children, but not necessarily leaves, meaning the returned tasks themselves may spawn tasks. This task could also generate a mutated or modified task different from this task. It is perfectly reasonable for tasks in the returned list to be themselves be interdependent, but they should not be dependent on tasks not within this list.

Finalize anything after the task has been run.
This method should be called after a task has been run. The intended use of this method is to allow for any modification of this task prior to any dependent tasks being run. This would allow any parameters that were passed to dependent tasks as call-by-name to be finalized here. For example, we could have passed an Option[String] that is None until make it Some(String) in this method. Then when the dependent task's getTasks method is called, it can call 'get' on the option and get something.

Base class for all tasks, multi-tasks, and workflows.
Once a task is constructed, it has the following evolution: 1. Any tasks on which it depends are added (see ==>). 2. When all tasks on which it is dependent have completed, the getTasks method is called to create a set of tasks. This task becomes dependent on any task that is returned that is not itself. 3. When all newly dependent tasks from #2 are complete, as well as this task, the onComplete method is called to perform any light-weight modification of this task. 4. If a task failed during execution or within onComplete, the retry method will be called until the task no longer wishes to retry or succeeds.
