#40 Expand Row security to groups

[Kenneth Downs]

Right now row security operates entirely on user_id, either a column in a table or a cross-reference of users to some other value.

It would be nice to expand it to work on group membership. So instead of saying, "you can see any row that has your user_id", it would be, "you can see any row where you are a member of this group."

Likewise for row-level lookups, instead of saying, "You can see any row where this value appears in a lookup that names you" it would be, "You can see any row where this value appears in a lookup that names this group."
