History: RolePerms

Whenever you create a new Workspace Role, a new tiki group is created, named RolePerms-whatever-was-the-name-of-your-role
This group is where you have to assign permissions that you want your role will have on the workspace's objects.

So if you assign 'teacher' tiki_p_edit, he will be able to edit pages in the workspace, but not anywhere else.
This group doesn't need to be included in any other group.

(mmmh... maybe one can explain this better...)
These are not group perms, but a template for assigning object perms to
