[Arp] arp(x ?) extensions, ModelLocator...

[Rich Rodecker]

yeah...the main issue the ModelLocator solves is that the Commands
were set up to call methods on a particular View when it received a
result..which is not really a good solution.  Now the Commands should
update the ModelLocator, and the ModelLocator should broadcaste a
changed event...which is where Christophe's version of the
ModelLocator comes in, because the one that was already included in
teh default ARP package didnt do any broadcasting.

The two different arpx packages serve two completely different
purposes, (grant's sets up a Command Controller/System controller,
which is for mapping events to commands) , and I dont remember if any
of their subpackages are named the same...if not you can propbably
combine them into one package. I know that's a little confusing, but
just remember that they are two differnent people's extensions to ARP.

For now, I'd follow Aral's advice and learn it as it is now first. 
Then when it comes to make the changes you will understand why they
were made and how they make it easier.
