2D random walk mobility model.
Each instance moves with a speed and direction choosen at random with the user-provided random variables until either a fixed distance has been walked or until a fixed amount of time. If we hit one of the boundaries (specified by a rectangle), of the model, we rebound on the boundary with a reflexive angle and speed. This model is often identified as a brownian motion model.
ns3::RandomWalk2dMobilityModel is accessible through the following paths with Config::Set and Config::Connect:
No TraceSources are defined for this type.

The default implementation does nothing but return the passed-in parameter. Subclasses using random variables are expected to override this.

This method is called by Object::Dispose or by the object's destructor, whichever comes first.
Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e., for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose method.
It is safe to call GetObject from within this method.

This method is called only once by Object::Initialize. If the user calls Object::Initialize multiple times, DoInitialize is called only the first time.
Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject and AggregateObject from within this method.
