pyfact 0.8.4 – Towards photon_stream

The pixel_dataframe returned by fact.pixels.get_pixel_dataframe() contains two new columns: azimuth and zenith, which contain the mean "viewing direction" of each pixel in the sky. (It even takes into a the fact, that the FACT reflector is not really a thin-lense in first order approximation... nice, hu?)

Also we add a new module fact.geometry, which up to now only contains position a dict, telling you where on earth the FACT telescope is. But who knows ... maybe more will come later.
