actionlib: Provides a standardized interface for a task
The actionlib package provides a standardized interface for interfacing
with preemptible tasks. Examples of this include moving the base to a target
location, performing a laser scan and returning the resulting point cloud,
detecting the handle of a door, etc.
The values for the status of a goal are as follows:
- PENDING - The goal has yet to be processed by the action server

- SUCCEEDED - The goal was achieved successfully by the action server
- ABORTED - The goal was aborted by the action server
- PREEMPTING - Processing of the goal was canceled by either another goal, or a cancel request sent to the action server
- PREEMPTED - The goal was preempted by either another goal, or a preempt message being sent to the action server
- RECALLING - The goal has not been processed and a cancel request has been received from the action client, but the action server has not confirmed the goal is canceled
