docs: Removes a Neighbour by taking a brutal approach to remove all the
  proxy Subscriptions on this ME pointing at other Neighbours.
  
  This will not leave the Neighbour marked as deleted and wait for the
  delete message, it will simply zap everything in site.
  
  This will forward on any deregistration Events to other Neighbours.
  
  @param neighbourUUID The UUID for the Neighbour
  @param busId  The bus that this ME belongs to.
  @param transaction  The transaction for deleting the Neighbour
  
  @exception SIDestinationNotFoundException  Thrown if the Neighbour was not found
  @exception SIResourceException
