! Purpose: read user input and store it in the data structure.
!          Copy region topology to coarser grids.
!          Check user input.
!
! Description: none.
!
! Input: regions = dimensions and topology (finest grid).
!
! Output: regions = dimensions, topology and user input (finest grid).
!
! Notes: none.
