Pattern functions anySize() and anyColor() not implemented

Hello,

I can't seem to get anySize() or anyColor() working with the Pattern class, it looks like they are using it in this example from http://docs.google.com/gview?url=http%3A%2F%2Fgroups.csail.mit.edu%2Fuid%2Fprojects%2Fsikuli%2Fsikuli-uist2009.pdf

x = Pattern(image).exact() - works
   click (x)
x = Pattern(image).similar(0.8) - works
   click (x)
x = Pattern(image).similar(0.8).anyColor() - AttributeError: anyColor
   click (x)
x = Pattern(image).similar(0.8).anyColor().anySize() - AttributeError: anyColor
   click (x)

I would imagine this would be very helpful if they were actually working.

Thanks,

Jake
