! Purpose: calls routines for initialisation of RADI solutions
!
! Description: Initiate solution variables (qr, radInd, radCoef) to zero.
!              No initial work required for diffusion approximation method of 
!              radiation. For general (RTE) methods, angular discretization
!              is done once in initialisation, while directional weights are 
!              computed for each mesh configuration (once in initialisation and 
!              called again when the grid move).
!
! Input: iReg   = index of current region
!        region = data of current region
!
! Output: for diffusion approximation: none.
!         for general method (RTE): angular mesh and directional weights.
!
! Notes: none.
