[oats-sig] open gazer problems

Someone just reminded me of this too, if anyone wants to get their hands

Hi Simon. I rather optimistically took a stab at porting/rewriting
their visible-spectrum algorithm in python+numpy a while back, as I
dont have a matlab license (and it seems a bit strange that an open
source project requires an expensive license to run). I really like
their ideas, but its a shame about it being matlab only. I got
distracted when I discovered opengazer, but perhaps it would be worth
picking it up again, though it would possibly be just for the sake of
learning more.

Compiling it with Octave was another idea, but when I tried it didn't
quite support enough of matlab's functionality. Perhaps thats changed
now.
