 RS(	   s  Wrapper around a standalone Matlab application that implements aerosol
    backscatter and lidar ratio retrieval algorithm utilizing Raman lidar
    signals.

    Attributes:
      - 'lidarInputs': a pair of 'PreparedLidarInput' instances representing
        measurements for the source and Raman lidar channels. Source lidar
        measurement mey be either unpolarized or parallel-polarized.
      - 'ramanParams': a 'RamanParams' instance.

      - 'profileInitBackscatter', 'profileInitLidar': initial approximations to
        the aerosol profiles to be retrieved, or 'None's if default values
        should be used instead.
      - 'ratiosInit': initial approximations to backscatter ratios at the
        reference points (a list of 2 numbers), or 'None' if default values
        should be used instead.

      - 'hideIntermediateOutputs': 'True', if 'getAllRetrievalOutputs' method
        of this class should return only the last retrieval output instance
        (similar to 'getRetrievalOutput()'). This is 'False' by default.c         C   sG   t  j |  ƒ | |  _ | |  _ d  |  _ d  |  _ d  |  _ t |  _	 d  S(   N(
