stateful function

Generates an infinite, randomized path of coordinates in a geospatially bounded box.

Inputs:

• boundingBox: a geospatially bounded box defined by two points: the lower left point and the upper right point.
• All other parameters mirror those in waypoints generator.

Outputs:

• latitude: The latitude of the position.
• longitude: The longitude of the position.
• duration: The number of milliseconds between each point. Use this value to throttle the generator for speed-realism.
• heading: The navigational heading/bearing, in degrees, of the object.
