After struggling a bit with Auth, especially in terms of doing role
or group authentication, I thought I would post what I found out.
Basically each user belongs to a group (admin, calibration,
etc...) and I wanted to set the authorized controller functions for
each group in each individual
I also wanted to mention that if you try this out with a controller
called TestsController, the authentication doesn't seem to work -
everyone (even not logged on) is given access to all functions. I
found this out the hard way! That's why I renamed it to
TrestsController.
