ESMF_PointListDestroy Subroutine

  subroutine ESMF_PointListDestroy(pointlist, rc)
!
! !ARGUMENTS:
    type(ESMF_PointList), intent(inout) :: pointlist
    integer, intent(out), optional :: rc
!
! !DESCRIPTION:
!   Destroys an {\tt ESMF\_PointList}, releaseing the resources associated
!   with the object.
!
!   The arguments are:
!   \begin{description}
!   \item[pointlist]
!     The {\tt ESMF\_PointList} to be destroyed.
!   \item[{[rc]}]
!     Return code; equals {\tt ESMF\_SUCCESS} if there are no errors.
!   \end{description}
