Solve radiative transfer equation in two stream approximation

Note that Japanese and English are described in parallel.

Solve radiative transfer equation in two stream approximation. Analytic solution is used to calculate radiative flux in a homogeneous atmosphere in which the single scattering albedo and the asymmetry factor are constant. Radiative transfer equation is solved numerically with the method by Toon et al. (1989) to calculate radiative flux in an inhomogeneous atmosphere.

    ! Calculate radiative flux in a homogeneous scattering and absorbing atmosphere. 
    ! Analytical solution is used for calculation of radiative flux. 
    ! Radiative flux in a semi-infinite atmosphere is calculated if FlagSemiInfAtm 
    ! is .true.. If FlagSemiInfAtm is not given or is .false., radiative flux in a finite
    ! atmosphere (bounded by the surface) is calculated.
    !
    ! If FlagSL09 is .true., short wave radiative flux is calculated with the method by 
    ! Schneider and Liu (2009). 
    !
    ! See Meador and Weaver (19??), Toon et al. (1989), Liou (200?), and so on for
