/* Description of SCROTT object permissions system
* -----------------------------------------------
* Every object has an owner, zero or more additional members, and then there is the general
* public.
*
* OWNER = user OR group
* MEMBER = user
* OWNER MEMBERS OTHERS
* Permissions are: ------------------------------------------------
* 1. Access object GRANTED GRANTED MB #6
* 2. Modify object GRANTED MB #0 DENIED
* 3. Modify members GRANTED MB #1 DENIED
* 4. Modify permissions GRANTED DENIED DENIED
* 5. Access sub-objects GRANTED MB #2 MB #7
* 6. Create sub-objects GRANTED MB #3 MB #8
* 7. Modify sub-objects GRANTED MB #4 DENIED
* 8. Modify sub-objects' members GRANTED MB #5 DENIED
* 9. Modify sub-objects' permissions GRANTED DENIED DENIED
*
* 012345678
* EG: 001111000 = 120 --implies--> that members may access,create,and
* fully modify sub-objects. All other
* options are DENIED. This mask value
* of 120 is a recommended starting point.
*
* Permissions can be overridden down-stream, but permissions will cascade otherwise.
