! Purpose: compute source term due to radiation and added to RHS of fluid eqs.
!
! Description: For diffusion approximation, computing source term consists of:
!              - computing radiant energy flux (qr), added to RHS (ROSS/FLDSRC)
!              - computing radiant source term, added to RHS (FLDTRAN)
!              For general method of radiation modeling:
!              - computing radiation intensities I (heart of the method),
!              - computing radiant energy flux (qr) from I and added to RHS.
!
! Input: regions = data of all regions
!        iReg    = index of current region.
!
! Output: rhs of energy equation updated by RADI source term
!
! Notes: effective temperature is computed for all, but for general method
!        and full-FLD it is used merely for comparison and reference, not 
!        employed in the computation.
