! Purpose: get type of boundary vertices, needed to correct global%tofluNedges
!
! Description: the 'type' has 6 components which have initial value of zero. 
!              Component 2, 4, or 6 switches to 1 if the lbound value of the 
!              patch where the boundary vertex resides matches the component 
!              number. This way, the points to be corrected for nEdges can
!              be distinguished. Only non-connecting patches are processed, 
!              as the procedure concerns only the global boundary vertices.
!              The correction of nEdges itself is performed in subroutine
!              CorrectNedges.
!
! Input: iReg    = region number
!        regions = data for all regions
!
! Output: global%tofluBType
!
! Notes: none.
