! `MAPL_LatLonGridCreate` --- Create regular Lat/Lon Grid
!
! This routine creates a distributed ESMF grid where the horizontal
! coordinates are regular longitudes and latitudes. The grid is
! created on the user specified **VM**, or on the current VM if the user
! does not specify one. The layout and the coordinate information can
! be provided with a `ESMF_Config attribute, a resource file name
! or specified through the argument list.
!
!### Using resource files
! The **resource file** has a syntax similar to a GrADS
! control file.  Here is an example defining a typical GEOS-5 1x1.25
! grid with 72 layers:
!
!```
!       GDEF: LatLon
!       IDEF: 32
!       JDEF: 16
!       LDEF:  1
!       XDEF: 288 LINEAR -180. 1.25
!       YDEF: 181 LINEAR -90. 1.
!       ZDEF:  72 LINEAR 1 1
!```
! More generally,
!```
!       GDEF: LatLon
!       IDEF: Nx
!       JDEF: Ny
!       LDEF: Nz
!       XDEF: IM_World XCoordType BegLon, DelLon
!       YDEF: JM_World YCoordType BegLat, DelLat
!       ZDEF: LM_World ZCoordType 1        1
!```
!
! The attribute **GDEF** must always be `LatLon` for  Lat/Lon grids.
! The remaining parameters are:
!- **Nx** is the number of processors used to decompose the X dimension
!- **Ny** is the number of processors used to decompose the Y dimension
!- **Nz** is the number of processors used to decompose the Z dimension;
!   must be 1 for now.
!- **IM_World** is the number of longitudinal grid points; if `IM_World=0` then
!   the grid has no zonal dimension.
!- **XCoordType** must be set to LINEAR
!- **BegLon** is the longitude (in degrees) of the {\em center} of the first gridbox
!- **DelLon** is the constant mesh size (in degrees); if `DelLon<1` then a
!   global grid is assumed.
!- **JM_World** is the number of meridional grid points; if `JM_World=0` then
!   the grid has no meridional dimension.
!- **YCoordType** must be set to LINEAR
!- **BegLat** s the latitude (in degrees) of the *center* of the first gridbox
!- **DelLat** s the constant mesh size (in degrees); if `DelLat<1` then a
!   global grid is assumed.
!- **LM_World** is the number of vertical grid points; `LM_World=0` then the grid has no
!   vertical dimension.
!
! As of this writing, only the size of the vertical grid `LM_World` needs to be specified.
!
!### Passing an ESMF Config
! The `ESMF_Config` object `Config`, when specified, must
! contain the same information as the resource file above.
!
!### Providing parameters explicitly through the argument list
! Alternatively, one can specify coordinate information in the argument
! list; their units and meaning is as in the resource file above. In
! this case you must specify at least `Nx, Ny, IM_World, JM_World`, and
! `LM_World`. The other parameters have default values
!- **BegLon** defaults to -180. (the date line)
!- **DelLon** defaults to -1. (meaning a global grid)
!- **BegLat** defaults to -90. (the south pole)
!- **DelLat** deaults to -1. (meaning a global grid)
!
!### Restrictions
! The current implementation imposes the following restrictions:
!1. Only uniform longitude/latitude grids are supported (no Gaussian grids).
!2. Only 2D Lon-Lat or 3D Lon-Lat-Lev grids are currently supported
!   (no Lat-Lev or Lon-Lev grids supprted yet).
!3. No vertical decomposition yet (`Nz=1`).
!
!### Future enhancements
! The `IDEF/JDEF/LDEF` records in the resource file should be
! extended as to allow specification of a more general distribution.
! For consistency with the `XDEF/YDEF/ZDEF` records a similar
! syntax could be adopted. For example,
!
!```
!       IDEF 4   LEVELS  22 50 50 22
!       XDEF 144 LINEAR -180 2.5
!```
! would indicate that longitudes would be decomposed in 4 PETs,
! with the first PET having 22 grid points, the second 50 gridpoints,
! and so on.
