	Hello. Jesse.
All day try to understand ACL, Groups, Rights, Principals with no hope 
on success.

Some questions:
I. Table ACL:
	1) ACL.PrincipalType could be == 'Group' and in this case 
ACL.PrincipalId -> Groups.id, is this rught?
	2) In other cases ACL.PrincipalId -> Principals.id?
	3) Each row in this table it is '<Something> have <RightName> right on 
object #<ObjectId>. This object have type <ObjectType>'. Is previose 
right and how to figure out what is <Something>?

II. Table Principals:
	1) First of all, it's bad naming ACL.PrincipalType and 
Principals.PrincipalType
	2) PrincipalType always =~ /Group|User/ ?
	3) If select * from ACL A, Principals P where A.PrincipalType !='Group' 
and A.PrincipalId = P.id and P.PrincipalType = 'Group'; not empty then 
what such records mean?

III. Table Groups:
	1) Where Groups <-> Groups links stored?
	2) Where Groups <-> Users links stored?
	3) How to define what <Instance> is mean?


	Best Regards. Ruslan.
