Practical usage of drsview to generate datasets which can be opened programmatically

[bnlawrence]

We have a bucket that we can inspect as follows:

drsview -c Period -s Variant=r1i1p1f1 -s Frequency=6hrPt

which results in

Variable : ['epv', 'hfnpuv', 'hus', 'ps', 'psl', 'ta', 'tmfurg', 'tmfvrg', 'ua', 'va', 'wa', 'zg', 'zg500']
Source : ['HadGA7EA-N1280']
Experiment : ['highresSST-present']
Variant : ['r1i1p1f1']
Frequency : ['6hrPt']
Period : [1979-03-01T0600 ... 2000-12-01T0600] (len=258)
nFields : ['N120']

Ideally we'd be able to do:

drsview -c Period -s Variant=r1i1p1f1 -s Frequency=6hrPt :: ls

which would generate a file listing

or even

drsview -c Period -s Variant=r1i1p1f1 -s Frequency=6hrPt > r1i1f1p1_6hrPt.cfa

which would download a CFA file we could use to manipulate the data.
