added option for dry run

[doutriaux1]

which means no computations (just read in data)
fix #320

[doutriaux1]

@gleckler1 should be what you want.

[doutriaux1]

@gleckler1 is that what you wanted?

[gleckler1]

@doutriaux1 @durack1 its ok for now, so I'm ok to add it to master. Later we'll want to improve on it as it prints out stuff that does not relate to errors (e.g., "obs shape is") and at some point Paul can make it more of a log file.

@doutriaux1 is this good to go - tests are failing, does this also need master merged in?

[doutriaux1]

yp. I'm on it

[durack1]

@doutriaux1 is this dead - or does it need to be rebased?

[gleckler1]

@doutriaux1 maybe it has been replaced by the recently added '-t' option ?

[doutriaux1]

@durack1 let me update the branch.

[doutriaux1]

@durack1 at your convenience

[durack1]

Geez @doutriaux1 even pep8'd.. We might have to create that Robust label after all.. I'll wait for a green travis before merging, all looks good to me
