! Purpose: Prepare data structure for ROCFLU.
!
! Description: None.
!
! Input: 
!   global              Pointer to global type
!
! Output: None.
!
! Notes: 
!   1. Allocation for regions on each level starts from 0, which is used 
!      to store undecomposed grid on finest level
!   2. The allocation of the regions was removed from this routine and put 
!      into separate routine because compilation of this routine with 
!      optimization took a very long time and it was determined that the 
!      compilation of the allocation statement was responsible. This was
!      likely due to compiler trying to optimize the allocation as it was 
!      inside a DO-loop. Putting allocation into separate routine (without 
!      DO-loop) will break optimization.
