Title: Rename error to uncertainty in NDData 

As mentioned in #415, I've renamed any `error` names to `uncertainty`. Some of the class names seem extremely long, so I am open to suggestions there. I think @eteq mentioned perhaps:

StandardDeviationUncertainty --> StdDevUncertainty

but I'm ok with it either way.

For the record, I am **against** shortening the `NDData` keyword from `uncertainty` to `unc`.
