! !DESCRIPTION:
! This routine sets the default values of the lwidth, uwidth, and align
! based on the user's passed in values for these.
!
! The arguments are:
! \begin{description}
! \item[{[lWidthIn]}]
!     The lower width from the user.
! \item[{[uWidthIn]}]
!     The upper width from the user.
! \item[{[alignIn]}]
!     The lower width from the user.
! \item[{[lWidthOut]}]
!     The lower width based on user input.
! \item[{[uWidthIn]}]
!     The upper width based on user input.
! \item[{[alignIn]}]
!     The lower width based on user input.
! \item[{[rc]}]
!      Return code; equals {\tt ESMF\_SUCCESS} if there are no errors.
! \end{description}
