! Purpose: deallocate memory for variables associated with buffer datastructure 
!          of the corner and edge cells for all active regions.
!
! Description: none.
!
! Input: regions   = all regions,
!        iReg      = region number.
!
! Output: region%level%cornerCells(:)%bufferExchPlag = corner cell buffers
!         region%level%edgeCells(:)%bufferExchPlag   =   edge cell buffers
!
! Notes: none.
