[Dev] Proposal for new automation architecture

Having written my first functional test yesterday I have some thoughts. 
The biggest problem I encountered when trying to write and debug tests 
is navigating all the layers:

my test <-> CATS <-> CPIA Script <-> Chandler

Fortunately I'm very familiar with Chandler, somewhat familiar with CPIA 
Script and CATS is small enough to grock without much effort. However, I 
suspect most developers would find all the layers daunting and trying to 
debug things would only make it worse. I think it would be preferable to 
make the small changes necessary to CPIA Script to make it appropriate 
for testing instead of adding another layer, e.g. CATS. Similarly, I 
think it's preferable to modify Chandler to eliminate some of CPIA Script.
