A dataset containing Grid objects. @author caron
ucar.nc2.dt.grid.GridDataset
Make a NetcdfDataset into a collection of GeoGrids with Georeferencing coordinate systems.

A variable will be made into a GeoGrid if it has a Georeferencing coordinate system, using GridCoordSys.isGridCoordSys(), and it has no extra dimensions, ie GridCoordSys.isComplete( var) is true. If it has multiple Georeferencing coordinate systems, any one that is a product set will be given preference.
Example:
```
 GridDataset gridDs = GridDataset.open (uriString); List grids = gridDs.getGrids(); for (int i=0; i<grids.size(); i++) { GeoGrid grid = (Geogrid) grids.get(i); } 
```
