hilbertCurve            calculate finite approximations of the Hilbert
                        curve
hilbertImage            Produce a matrix that visualizes a long data
                        vector along a Hilbert curve
makeRandomTestData      generate a long vector of example data that is
                        suitable to demonstrate the Hilbert curve
                        visualisation
makeWiggleVector        generate a "wiggle vector" from start/end/value
                        data
plotHilbertCurve        Plotting the Hilbert curve (for demonstation
                        purposes).
plotLongVector          A simple function to plot a very long vector.
showHilbertImage        display a hilbert
shrinkVector            shrink a vector by partitioning it into bins
                        and taking the maxima in the bins
