/*  Provides the essentials of a waypoint, namely its position and its
    range of influence. This class can be extended for particular kinds
    of waypoint, eg: mountain, city, lake, fork in a river, gas holder,
    tower whose co-ordinates are known. Mainly, however a waypoint will
    be a purpose-built radio aid such as a VOR, TACAN, ILS or marker. */
