! !DESCRIPTION:
!    This method gets a Fortran pointer to the piece of memory which holds the
!    coordinate data for the given coordinate and stagger locations on the given local DE.
!    This is useful, for example, for setting the coordinate values in a Grid, or
!    for reading the coordinate values. Eventually this method will be overloaded
!    for the full range of ESMF supported types and dimensions.
!
!     The arguments are:
!     \begin{description}
!     \item[{grid}]
!          Grid to get the information from.
!     \item[{coordDim}]
!          The coordinate dimension to get the data from (e.g. 1=x).
!     \item[{staggerloc}]
!          The stagger location to get the information for.
!          Please see Section~\ref{const:staggerloc} for a list
!          of predefined stagger locations. If not present, defaults to
!          ESMF\_STAGGERLOC\_CENTER.
!     \item[{[localDE]}]
!          The local DE for which information is requested. {\tt [0,..,localDECount-1]}.
!          For {\tt localDECount==1} the {\tt localDE} argument may be omitted,
!          in which case it will default to {\tt localDE=0}.
!     \item[{farrayPtr}]
!          The pointer to the coordinate data.
!     \item[{[datacopyflag]}]
!          If not specified, default to {\tt ESMF\_DATACOPY\_REFERENCE}, in this case
!          farrayPtr is a reference to the data in the Grid coordinate arrays.
!          Please see Section~\ref{const:datacopyflag} for further description and a
!          list of valid values.
!     \item[{[exclusiveLBound]}]
!          Upon return this holds the lower bounds of the exclusive region.
!          {\tt exclusiveLBound} must be allocated to be of size equal to the coord dimCount.
!          Please see Section~\ref{sec:grid:usage:bounds} for a description
!          of the regions and their associated bounds and counts.
!     \item[{[exclusiveUBound]}]
!          Upon return this holds the upper bounds of the exclusive region.
!          {\tt exclusiveUBound} must be allocated to be of size equal to the coord dimCount.
!          Please see Section~\ref{sec:grid:usage:bounds} for a description
!          of the regions and their associated bounds and counts.
!     \item[{[exclusiveCount]}]
!          Upon return this holds the number of items in the exclusive region per dimension
!          (i.e. {\tt exclusiveUBound-exclusiveLBound+1}). {\tt exclusiveCount} must
!          be allocated to be of size equal to the coord dimCount.
!          Please see Section~\ref{sec:grid:usage:bounds} for a description
!          of the regions and their associated bounds and counts.
!     \item[{[computationalLBound]}]
!          Upon return this holds the lower bounds of the stagger region.
!          {\tt computationalLBound} must be allocated to be of size equal to the coord dimCount.
!          Please see Section~\ref{sec:grid:usage:bounds} for a description
!          of the regions and their associated bounds and counts.
!     \item[{[computationalUBound]}]
!          Upon return this holds the upper bounds of the stagger region.
!          {\tt exclusiveUBound} must be allocated to be of size equal to the coord dimCount.
!          Please see Section~\ref{sec:grid:usage:bounds} for a description
!          of the regions and their associated bounds and counts.
!     \item[{[computationalCount]}]
!          Upon return this holds the number of items in the computational region per dimension
!          (i.e. {\tt computationalUBound-computationalLBound+1}). {\tt computationalCount}
!          must be allocated to be of size equal to the coord dimCount.
!          Please see Section~\ref{sec:grid:usage:bounds} for a description
!          of the regions and their associated bounds and counts.
!     \item[{[totalLBound]}]
!          Upon return this holds the lower bounds of the total region.
!          {\tt totalLBound} must be allocated to be of size equal to the coord dimCount.
!          Please see Section~\ref{sec:grid:usage:bounds} for a description
!          of the regions and their associated bounds and counts.
!     \item[{[totalUBound]}]
!          Upon return this holds the upper bounds of the total region.
!          {\tt totalUBound} must be allocated to be of size equal to the coord dimCount.
!          Please see Section~\ref{sec:grid:usage:bounds} for a description
!          of the regions and their associated bounds and counts.
!     \item[{[totalCount]}]
!          Upon return this holds the number of items in the total region per dimension
!          (i.e. {\tt totalUBound-totalLBound+1}). {\tt totalCount} must
!          be allocated to be of size equal to the coord dimCount.
!          Please see Section~\ref{sec:grid:usage:bounds} for a description
!          of the regions and their associated bounds and counts.
!     \item[{[rc]}]
!          Return code; equals {\tt ESMF\_SUCCESS} if there are no errors.
