New UGRID netcdf format v0.9

An IOOS working group led by Dr. Rich Signell have been working on a standard for unstructured grids. The latest is v0.9 as found [here https://github.com/ugrid-conventions/ugrid-conventions]

A few SELFE user groups have either built their own tools that use this new format or are working on this. Below is a summary of progress so far (as well as links if available):

• CAL-DWR (Eli Ateljevich et al): have built a VisIT plug-in for the native binary and v0.9 format
• MetOcean, NZ (Brett Beamsley): have made attempt to output
• Haihua Xu (Nat. Univ Singapore): have built a package (including VisIT) based on some older UGRID netcdf standard, for ELCIRC and SELFE;
• Joseph Zhang (OHSU & VIMS): the combine scripts can optionally output into netcdf format based on an older UGRID standard proposed >8 years ago;
