post future everything commit

1) Live/interactive version of one or two of the algorithms. I'd vote
for IResponse, RelaxRate and ColorMulti as the ones to do live on the
laptop.  David is looking at this...

2) The frame skipping issue remains.  I looked at this while travelling
today, but couldn't figure it out.  We're still saving out meshes at
about half the rate of them being created.

3) The following three analyses do exactly the same thing currently,
and it would be good if they had something approaching a real analysis
happening.  Right now it's just a simple z-map in black and white with
some noise on top and lighting... kind of pretty but bit boring
currently:
	ShapeFromShadingAnalysis
	CamNoiseAnalysis
	ShadowScapesAnalysis
