Thank you Marcus, for your answer above.
As for #2, now it worked well. I just mistyped a function name which was thus 
not 
recognized.

As for #1, Could you please advise exactly what kind of codes and where should 
I 
insert in order to create 2 probe maps in TemplateModelSwarm.[hm]?
My guess is you are mentioning "-getProbeMapFor: (Class) aClass", bug I don't 
know how it works.

Thank you.
