[thredds] Any way to change a NetCDF variable name using NcML?

[John Caron]

rename rh to ReletiveHumidity:

  <variable name="ReletiveHumidity" orgName="rh" />

see example 3 of

  http://www.unidata.ucar.edu/software/netcdf/ncml/v2.2/Tutorial.html

However, aggregation in 2.2 has trouble when the variable is renamed. As you may 
have guessed, 4.0 will fix that.
