[Building Sakai] SAKAI_REALM_FUNCTION

[Steve Swinsburg]

Spot on, thats how it still works.

There is also an additional method signature that allows you to mark a registered function as userMutable or not.

When the authz group is saved (DbAuthGroupService.java save()) it checks all the functions it needs with checkFunctionName(), which is where they get inserted in the db for the first time, and by that insert, allocated a number.  The number is what gets stored with the authz.
