563	Updated and corrected several Matlab scripts	arango	arango	"Several Matlab scripts where updated.  The processing scripts '''roms2roms.m''' and '''obc_roms2roms.m''' have the incorrect calls to the '''nc_vinfo''' function. Many thanks to John Wilkin to remind me of these typos. 

In addition several new scripts were introduced:

 * '''d_core2_frc.m''': Driver template script showing how to create ROMS forcing NetCDF file(s) using ROMS metadata structure. The data source is the CORE 2 Global Air-Sea Flux Dataset. Notice that the original data set is sampled for the Gulf of Mexico (GOM).

 * '''netcdf/check_metadata.m''': Checks ROMS metadata structure for consistency and fills unassigned fields. This structure will be used elsewhere to create NetCDF files in a compact way.

 * '''netcdf/nc_append.m''': Defines/appends new variables to an existing NetCDF file. The variable(s) metadata is provided in input structure, which includes information about variable type, dimensions and attributes.

 * '''roms_metadata.m''': Sets metadata structure for requested ROMS NetCDF variable. The structure contains the same fields that are returned by '''nc_inq''' or native interface '''ncinfo'''. This can be used elsewhere to create a NetCDF file in a compact way.

 * '''plot_field.m''': Plots requested ROMS variable from input history NetCDF file. This function is very useful when debugging a ROMS application. The plotting is not that fancy but it provides enough information for browsing ROMS variables very quickly. The location of the minimum is marked with a filled magenta circle whereas the maximum is marked with a filled magenta square.  It also draws the coastline, if the data is available in the grid file or structure. 

Notice that the '''roms_metadata''' function builds a structure with similar information as in ROMS '''varinfo.dat'''.  The strategy here is to create a structure that can be used with '''nc_create''' to generate ROMS input NetCDF files in a compact way.  The driver template '''forcing/d_core2_frc.m''' provides an example of how the ROMS metadata structure is used to create several atmospheric forcing NetCDF files. It creates a single NetCDF file per forcing field.  This is kind of nice since creating NetCDF file is too verbose and requirse hundreds of lines of coding.  Here this is done in a very compact and generic way and with few lines.  In addition, it provides the correct CF compliance.

I assume the the function '''roms_metadata''' will continue evolving in the future as we add more fields."	upgrade	new	major	Matlab Processing Scripts	Matlab	3.6
