Yuck =) That goes against the idea of mixins...

if I where to use this mixin with say... SubSiteLayout ... ah well you get the 
idea =)

Is there a way to test if a method exists within a class?

If so... the code PSP creates could recurse through the parent classes looking 
for the first class that implements the awake method.

so you might end up with something like this in your generated class:

def awake(self.trans):
    for baseclass in self.__class__.__bases__
        if ... (code to check if the method exists?):
            baseclass.awake(self, trans)
            break
    self.initPSP()

This should should hopefully make calling the awake method simular to how 
Python looks up methods in parent classes.... So the first class to implement 
the method is the one which gets used for that method.
