%Docstring
 This is an implementation of a Clough-Tocher interpolator based on a triangular tessellation. The derivatives orthogonal to the boundary curves are interpolated linearly along a triangle edge.*

  protected:
    void init( double x, double y );
%Docstring
Finds out, in which triangle the point with the coordinates x and y is

%Docstring
Calculates the Bernsteinpolynomials to calculate the Beziertriangle. 'n' is three in the cubical case, 'i', 'j', 'k' are the indices of the controllpoint and 'u', 'v', 'w' are the barycentric coordinates of the point
