GENIE Gridspec Diagrams Mosaic

A mosaic consists of one or more "mosaicgrids". A mosaicgrid can either be a child mosaic, or a grid tile. Using this recursive mosaic concept, it is possible for a gridspec to represent a hierarchy or "tree" of grids for an entire framework of Earth system models, with each grid eventually ending with tiles as the "leaves". An optional grid descriptor may be used to apply a description to all tiles within a mosaic grid, e.g. "regular_lat_lon", "cubed_sphere".

Note: the gridspec overview contains introductory and background information on the gridspec; more detailed information can be found in Balaji's gridspec document on the Earth System Curator website.
