    The perception module of a GTU based on lanes. It is responsible for perceiving (sensing) the environment of the GTU, which includes the locations of other GTUs. Perception is done at a certain time, and the perceived information might have a limited validity. In that sense, Perception is stateful. Information can be requested as often as needed, but will only be recalculated when asked explicitly. This abstract class provides the building blocks for lane-based perception.
    Perception for lane-based GTUs involves information about GTUs in front of the owner GTU on the same lane (the 'leader' GTU), parallel vehicles (important if we want to change lanes), distance to other vehicles on parallel lanes, as well in front as to the back (important if we want to change lanes), and information about obstacles, traffic lights, speed signs, and ending lanes.

    This class allows PerceptionCategorys that are either eager or lazy. All categories will have the updateAll method invoked prior to an operational plan being determined. Categories may ignore this and instead evaluate results only when the tactical planner requests them.
