There were various random "documentation" tidbits, all for rados,
on the main readme. As these are neither comprehensive nor complete
I am moving them to a seperate page and calling them "hints" which
seem to be closer to what they are.
Eventually, we could include more comprehensive examples in the
docs/ directory.
