[Rnomads-user] Problem reading archived RUC ANL data shen local.dir specified

[Daniel Bowman]

I fixed the issue and also made things simpler by just having the grib
downloader return the full file name, so you can just say:

ReadGrib(grib.info[[1]]$file.name, levels, variables)

no matter where the files listed in grib.info are located.

Thanks for bringing this to my attention!  It will be in the next release,
perhaps this weekend.
