### Description
* Contributed by: Lars Friedrich

A simple example that shows how to use vtkTupleInterpolator for the purpose of interpolating 1D functions. Internally the program investigates two functions: *sine* and *Runge* function with sparsely distributed supporting points. The application uses different interpolation modes: '''linear''', '''cardinal spline''' and '''Kochanek spline'''. Moreover, the example offers the "--csv-output" (or "-co") option which causes the program to generate CSV-sheets reflecting the interpolated data. In order to demonstrate the spline interpolation behavior at the edge regions, we use the '''open''' and '''closed''' interval spline options as well. For example, a Kochanek-interpolation of the Runge function:

### Program Usage

./1DTupleInterpolation [](options)

  -h or --help ... print this short help
  -nv or --no-verbose ... no verbose messages to std::cout
  -co or --csv-output ... CSV (comma separated values) file outputs

  **NOTE:** optional arguments are case-sensitive!
