waypoint list mobility model

I made a new "waypoint list" mobility model, to help a student working with NS-3. It's similar to the random waypoint model, but in this case the waypoints are deterministic and taken from a list given by the programmer. Let me know if there is interest in including this model in ns-3-dev.

I wonder if this patch is superseded by the current src/mobility/position-allocator.h code, more specifically: ListPositionAllocator. If so, can you confirm so I can close this bug as INVALID ?

WaypointListMobilityModel has a list of positions through which a single node has to travel. So, no, I don't think they overlap.

But RandomWaypointMobilityModel now uses another PositionAllocator object to allocate each destination position.

Hmm... OK. Then RandomWaypointMobilityModel becomes a misnomer, since it may not be random at all :) But, yes, in this case, which is news to me, WaypointListMobilityModel becomes redundant.
