!Description:

  Header file pixel.h
  Defines "pixel_in" and "pixel_out" structures.

  The structure variables of type "pixel_in" contain all necessary
  inputs for generating a cloud mask for any given pixel.

  The structure variables of type "pixel_out" contain all output data
  pertaining to any given pixel, including the final confidence of
  clear sky.
