#clear ⇒ Object
Clears all registrations from the registry. This will not delete the particles or the force generators themselves, just the records of their connection.

#remove(particle, force_generator) ⇒ Object
Removes the given registered pair from the registry. If the pair is not registered, this method will have no effect.
