NestedIntervalUtils - Global

The NestedIntervalUtils class provides methods for managing the planned task tree structure for the planned task [planned_task] table.

This API requires that the planned_task table has integer fields called a11, a12, a21, a22, level, and child_position. The table must also have three reference fields called parent, root_id, and top_task.

Use these methods to manage the tree structure for the planned_task table in the services interface.
