Energy rating (IEC 61853)
=========================

This module implements the energy rating calculations
described in standard IEC 61853.

The four main calculation steps are:

#. Calculate the angle-of-incidence correction using the functions:

   * martin_ruiz()
   * martin_ruiz_diffuse()

#. Evaluate the spectral factor using the functions:

   * convert_to_banded()
   * calc_spectral_factor()

#. Estimate the operating temperature using the function:

   * faiman()

#. Determine the module efficiency using the class:

   * BilinearInterpolator()
