Sequential list processing
--------------------------
If a list ends with `--`, the top level of tasks will be treated as a priority queue and the most important will be labeled `@next_action`.
Importance is determined by:
1. Priority
2. Due date
3. Order in the list
`@next_action` waterfalls into indented regions. If the top level task that is selected to receive the `@next_action` label has subtasks, the same algorithm is used. The `@next_action` label is only applied to one task.
Importance is determined by order in the list
Parallel list processing
