Code relating to the topic of Contour plot.
// AnalyticTetrationBaseSqrt2u00.png // (click at the figure to see the description)
// In order to generate the figure above, you need the plotter routines
// ContourPlot/code/ado.cin , which makes the header of the eps file, and
// ContourPlot/code/conto.cin, witch draws there the contour lines.
// With these routines, you may compile and execute the source below
