          This uses the function getRCIfromSDandAlpha() in my CECPfuns R package to get the RCI
          but the maths is trivial and straight out of the original work on the RCI.
          The code combines that RCI with the standard formula for the Confidence Interval (CI)
          to give what I am calling a 'plausible interval' around that RCI based on the width
          of the CI you have requested.  Until the n is large, the interval is wide which I think
          should help us understand this.  Deciding when your dataset size is too small to give
          a usably tight plausible interval for the dataset RCI and hence that it would be better
          to use some 'referential' RCI is an interesting challenge.  I'll do some modelling to
          address that soon.
