The ActionServer is a helpful tool for managing goal requests to a node. It allows the user to specify callbacks that are invoked when goal or cancel requests come over the wire, and passes back GoalHandles that can be used to track the state of a given goal request. The ActionServer makes no assumptions about the policy used to service these goals, and sends status for each goal over the wire until the last GoalHandle associated with a goal request is destroyed.
