-- Poll for player proximity to a point in space.
-- argument trigger: a table containing:
-- location: The location, OR
-- anchor: the pilot to use as the anchor for the trigger area
-- radius: The radius around the location or anchor

-- funcname: The name of the function to be called when the player is in proximity.
