[APBeta] Global observations script

[Paul Rodman]

Unfortunately, the REALbasic language subset used in AP scripting does  
not (currently) allow me to determine the type of exception, or its  
location. I have been leaning on the vendor for (literally) years to  
sort out the problem. At least it's better than V1 where an exception  
just caused a hard crash...

Hopefully in the future this situation will improve.

Meantime, the way I go about tracking these things down is one or more  
of the following:

a: Comment out chunks of code until it doesn't get an exception, and  
narrow it down.
b: Put debugging comments (e.g. debug "A", debug "B", etc.) every  
dozen lines and see with debug statement was the last one to report in  
successfully.
c: put a "return" statement in the main() method near the start. If  
the code runs to that point, move the statement down another couple of  
lines, etc.
