[Tutor] Can I speed this up?

[Kent Johnson]

The import psyco can be anywhere. The psyco.bind(factorsOfInteger) has to 
come after the definition of factorsOfInteger or you will get a NameError.

I've been monkeying around with a version of this, I'll post it when I get 
time to write it up...the key for me was instead of isPrime() I have find 
findFactor()
