! Purpose: calculate the centroid of a cell.
!
! Description: file contains the following subroutines:
!
!  - CentroidTetra   = tetrahedron
!  - CentroidPyramid = pyramid
!  - CentroidPrism   = prism
!  - CentroidHexa    = hexahedra
!
! Input: xyzNodes = coordinates (1st index) of the nodes (2nd index) of the
!                   control volume (must be ordered!).
!
! Output: cofgX,cofgY,cofgZ = x-,y-,z-coordinate of the centroid.
!
! Notes: none.
