These are static KML files which have contain NO hydrodynamic/thermodynamic/ice data.

They are intended to be used *in conjunction* with the FVCOM netCDF output to visualize the data.  See the R examples in the NOAA GLERL code gallery for example usage:  https://noaa-glerl.github.io/intro.html

The files represent the FVCOM grids as follows:
	- "nodes" the vertices of the grid (spatialPoints)
	- "elems"  the elements/cells of the grid (spatialPolygons)
	- "voronoi" the voronoi/theissen polygons corresponding to the nodes 
					(useful for plotting heat maps of scalar data stored on nodes)
