! !DESCRIPTION:
!
! This method creates a single tile, regularly distributed grid
! (see Figure \ref{fig:GridDecomps}).
! To specify the distribution, the user passes in an array
! ({\tt regDecomp}) specifying the number of DEs to divide each
! dimension into. The array {\tt decompFlag} indicates how the division into DEs is to
! occur.  The default is to divide the range as evenly as possible.
!
! The arguments are:
! \begin{description}
! \item[{[coordTypeKind]}]
!     The type/kind of the grid coordinate data. All {\em numerical} types
!     listed under section~\ref{const:typekind} are supported.
!     If not specified then defaults to ESMF\_TYPEKIND\_R8.
! \item[{[regDecomp]}]
!      List that has the same number of elements as {\tt maxIndex}.
!      Each entry is the number of decounts for that dimension.
!      If not specified, the default decomposition will be petCountx1x1..x1.
! \item[{[decompflag]}]
!      List of decomposition flags indicating how each dimension of the
!      tile is to be divided between the DEs. The default setting
!      is {\tt ESMF\_DECOMP\_BALANCED} in all dimensions. Please see
!      Section~\ref{const:decompflag} for a full description of the
!      possible options. Note that currently the option
!      {\tt ESMF\_DECOMP\_CYCLIC} isn't supported in Grid creation.
! \item[{[minIndex]}]
!      The bottom extent of the grid array. If not given then the value defaults
!      to /1,1,1,.../.
! \item[{maxIndex}]
!      The upper extent of the grid array.
! \item[{[connflagDim1]}]
!      Fortran array describing the index dimension 1 connections.
!      The first element represents the minimum end of dimension 1.
!      The second element represents the maximum end of dimension 1.
!      If array is only one element long, then that element is used
!      for both the minimum and maximum end.
!      Please see Section~\ref{const:gridconn} for a list of valid
!      options. If not present, defaults to ESMF\_GRIDCONN\_NONE.
!     [CURRENTLY NOT IMPLEMENTED]
! \item[{[connflagDim2]}]
!      Fortran array describing the index dimension 2 connections.
!      The first element represents the minimum end of dimension 2.
!      The second element represents the maximum end of dimension 2.
!      If array is only one element long, then that element is used
!      for both the minimum and maximum end.
!      Please see Section~\ref{const:gridconn} for a list of valid
!      options. If not present, defaults to ESMF\_GRIDCONN\_NONE.
!     [CURRENTLY NOT IMPLEMENTED]
! \item[{[connflagDim3]}]
!      Fortran array describing the index dimension 3 connections.
!      The first element represents the minimum end of dimension 3.
!      The second element represents the maximum end of dimension 3.
!      If array is only one element long, then that element is used
!      for both the minimum and maximum end.
!      Please see Section~\ref{const:gridconn} for a list of valid
!      options. If not present, defaults to ESMF\_GRIDCONN\_NONE.
!     [CURRENTLY NOT IMPLEMENTED]
! \item[{[poleStaggerLoc1]}]
!     Two element array describing the index dimension 1 connections.
!      The first element represents the minimum end of dimension 1.
!      The second element represents the maximum end of dimension 1.
!      If a pole, this describes which staggerlocation is at the pole at each end.
!      Please see Section~\ref{const:staggerloc} for a list
!      of predefined stagger locations. If not present, defaults to ESMF\_STAGGERLOC\_CENTER.

!     [CURRENTLY NOT IMPLEMENTED]
! \item[{[bipolePos1]}]
!     Two element array describing the index dimension 1 connections.
!      The first element represents the minimum end of dimension 1.
!      The second element represents the maximum end of dimension 1.
!      If a bipole, this gives the index position of one of the poles.
!      The other is half way around. If not present, the default is 1.
!     [CURRENTLY NOT IMPLEMENTED]
! \item[{[bipolePos2]}]
!     Two element array describing the index dimension 2 connections.
!      The first element represents the minimum end of dimension 2.

! \item[{[coordDep1]}]
!     This array specifies the dependence of the first
!     coordinate component on the three index dimensions
!     described by {\tt coordsPerDEDim1,2,3}. The size of the
!     array specifies the number of dimensions of the first
!     coordinate component array. The values specify which
!     of the index dimensions the corresponding coordinate
!     arrays map to. If not present the default is 1,2,...,grid rank.
! \item[{[coordDep2]}]
!     This array specifies the dependence of the second
!     coordinate component on the three index dimensions
!     described by {\tt coordsPerDEDim1,2,3}. The size of the
!     array specifies the number of dimensions of the second
!     coordinate component array. The values specify which
!     of the index dimensions the corresponding coordinate
!     arrays map to. If not present the default is 1,2,...,grid rank.
! \item[{[coordDep3]}]
!     This array specifies the dependence of the third
!     coordinate component on the three index dimensions
!     described by {\tt coordsPerDEDim1,2,3}. The size of the
!     array specifies the number of dimensions of the third
!     coordinate component array. The values specify which
!     of the index dimensions the corresponding coordinate
!     arrays map to. If not present the default is 1,2,...,grid rank.
! \item[{[gridEdgeLWidth]}]
!      The padding around the lower edges of the grid. This padding is between
!      the index space corresponding to the cells and the boundary of the
!      the exclusive region. This extra space is to contain the extra
!      padding for non-center stagger locations, and should be big enough
!      to hold any stagger in the grid. If this and gridAlign are not present then
!      defaults to 0, 0, ..., 0 (all zeros).
! \item[{[gridEdgeUWidth]}]
!      The padding around the upper edges of the grid. This padding is between
!      the index space corresponding to the cells and the boundary of the
!      the exclusive region. This extra space is to contain the extra
!      padding for non-center stagger locations, and should be big enough
!      to hold any stagger in the grid. If this and gridAlign are not present then
!      defaults to 1, 1, ..., 1 (all ones).
! \item[{[gridAlign]}]
!     Specification of how the stagger locations should align with the cell
!     index space (can be overridden by the individual staggerAligns). If
!     the gridEdgeWidths are not specified than this argument
!     implies the gridEdgeWidths. If the gridEdgeWidths are specified and this argument isn't
!     then this argument is implied by the gridEdgeWidths.
!     If this and the gridEdgeWidths are not specified, then defaults to
!    -1, -1, ..., -1 (all negative ones).
! \item[{[gridMemLBound]}]
!      Specifies the lower index range of the memory of every DE in this Grid.
!      Only used when indexflag is {\tt ESMF\_INDEX\_USER}. May be overridden
!      by staggerMemLBound.
! \item[{[indexflag]}]
!      Indicates the indexing scheme to be used in the new Grid. Please see
!      Section~\ref{const:indexflag} for the list of options. If not present,
!      defaults to ESMF\_INDEX\_DELOCAL.
! \item[{[petMap]}]
!       Sets the mapping of pets to the created DEs. This 3D
!       should be of size regDecomp(1) x regDecomp(2) x regDecomp(3)
!       If the Grid is 2D, then the last dimension is of size 1.
! \item[{[name]}]
!      {\tt ESMF\_Grid} name.
! \item[{[rc]}]
!      Return code; equals {\tt ESMF\_SUCCESS} if there are no errors.
