Re: [thredds] NetCDF Tools UI

Hi Nathan,

Currently, the netCDF ToolsUI will accept a single argument which must
be a URL to a THREDDS catalog. It opens that catalog in the "THREDDS"
tab. If the URL has a fragment identifier which is a valid dataset ID,
that dataset is selected and displayed in the "THREDDS" tab.

It would be a nice addition to allow a "-dap <dapURL>" argument which
would open the OPeNDAP dataset in the "Viewer" tab. I've added this to
our enhancements list.
