Title: #105 kolmogorov psf

I have implemented the generation of a long exposure atmospheric PSF from Kolmogorov turbulence. The size of the PSF is specified by the ratio of wavelength over the Fried parameter r0, where again the user is responsible for a consistent choice of units. This choice was motivated by striving for consistency between this module and the optics module.

A few issue we might want to discuss before merging:

* The unit tests are very basic at the moment. Other suggestions are welcome.

* atmosphere.py uses a few utility functions from optics.py. I think it would be better to move those from optics.py to a separate utilities.py file (the name is open to discussion, as this proposal, of course).
