[schooltool-dev] Merging of srichter's hierarchical term branch into trunk

[Jason Straw]

I am fine with breaking CanDo trunk as long as we can fix it.

I wanted to lock CanDo to a ST revision anyways for the 2007 release,
obviousally, the revision before this would be the point where CanDo
locked onto for 2007 (at least until December)

Can you and aelkner look over what would be required for CanDo to move
over to this for a 2007-12 or 2008 release?

This is also one of the few places where a loss of backward compat. is
acceptable to me.

I am CCing this to the CanDo Developers list for their feedback
