I've updated the SDG example to show exactly how Benedikt's suggestion
plays out.  The Organization class has the reaper queue, and all
subclasses of Agent2d can put things on it by calling `remove'.

`remove' takes the agent out of the space, informs the Organization it
is about to say goodbye (by scheduling a cleanup event for the next
timestep), and then Blammo!
