see the bottom for how I think it is to be understood.

This is a mess. I have a patch to change some of the assumptions by 
TurbineSecurity.getGlobalGroup(), and others by Profile.getGroup() since 
turbine hardwires the global group to be called global, and it is the 
group it will use for most of the API if no group is specified.

This patch is next on my list of patched to be sent here for review. 
Look for it in a couple hours.

Turbine seems to understand a group more as a "group of pages/resources" 
than as a group of users. This is the reason why users have a role "in a 
given group". The concept seems to be more similar to the HTTP Realm 
than to anything else. I.E., it is the context for a 
User->Role->Permission mapping.
