Individual users should be able to have different roles

[cegrif01]

Is it possible to have individual users have different roles? I see that get Caller::getCallerRoles() allows you to set what role you would like to have, but that is for all User instances.

I would like for getCallerRoles() to return a different value depending on who, I'm logged in as. I would like to query the db to return this value instead of having it hard coded. When I tried this approach, I realized that caller data and role data can never be set at the same time in the lock_permissions table.
