Detailed Description

This class extends CAbstractNavigator with the capability of following a list of waypoints.

By default, waypoints are followed one by one, but, if they are tagged with allow_skip=true and the derived navigator class supports it, the navigator may choose to skip some to make a smoother, safer and shorter navigation.

Waypoints have an optional target_heading field, which will be honored only for waypoints that are skipped, and if the underlying robot interface supports the pure-rotation methods.

Notes on navigation status and event dispatchment:

Navigation state may briefly pass by the IDLE status between a waypoint is reached and a new navigation command is issued towards the next waypoint.
sendNavigationEndEvent() will be called only when the last waypoint is reached.
Reaching an intermediary waypoint (or skipping it if considered so by the navigator) generates a call to sendWaypointReachedEvent() instead.
