CalibratedViews for resampled views on CalibratedRealIntervals

[ctrueden]

The CalibratedRealInterval class of imglib2-meta provides a RealInterval with one CalibratedAxis per dimension. With this information, it is possible to transform on demand from the source coordinate system into a target one. We just need a CalibratedViews static utility class, similar to regular Views, which provides an easy means of doing so.

@tpietzsch, we discussed you working on this eventually at our hackathon last April. But we still weren't quite far enough along on the CalibratedRealInterval work. I think that work is now ready to go, though, such that a CalibratedViews would become possible. @dietzc would also very much take advantage of this work in the KNIP project. Is it something you would have time to work on in the next six months? No worries if not; @dietzc and I will find some other way of getting it implemented. But since you are the Views guy we thought perhaps it make the most sense for you to take a crack at it.
