*
* COMMENTS:
* Definition for mob references
*
* These light weight classes use reference counting internally
* to allow you to track MOB * without having to worry about
* the MOB being deleted (you will then just get 0 back)
* It also allows swapping MOB * behind the users back,
* potentially compressing MOBs, etc. Also, you can always save/reload
* the raw MOBREFs rather than MOB * which don't save & load very well.
