fileout geotiff doesn't work for NCEP dataset

I fixed the initial problem quickly, as it was a programming error (not checking that the returned value from a search was not null). However, now it appears that the while the request runs to completion the response is not a geotiff that can be easily opened.

I suspect that this means that this is now blocked by Hyrax-263

I tried the URL http://testbed-12.opendap.org:8080/opendap/testbed-12/ncep/Global_0p25deg_best_hs002.nc.tiff?u-component_of_wind_isobaric[0][0][][] and it returned an empty file. I modified the URL to return ASCII and that worked.

Ah, Maybe the testbed-12 server was not updated... I'll run it locally to test after rebuilding.

Server rebuilt - data file still downloading...

Got the file and it seems to be OK - modulo Hyrax-263
