[netcdf-java] Creating unlimited dimension

[Christopher.Moore at noaa.gov]

Thanks Jeff,

Seems to work if I create thusly:

Dimension timedim = ncout.addDimension("TIME", 0, true, true, false);

though I'll try the addUnlimitedDimension method, too.

Trying to get faster read times with the version 2.2.22 over opendap.

Cheers,
Chris
