Re: test hdf5 files

I found some test data from the Aura satellite. This data is "real simulated"
datasets from prelaunch testing.  These were sent to us to help us test,
they aren't official NASA samples or anything like that.

If you want to try them, they are at:

  ftp://hdf.ncsa.uiuc.edu/pub/outgoing/mcgrath/HIR*.he5

Beware: one of them is pretty big!
