This is a class implementing n-dimensional scattered data interpolation. Function values need not be scalar, but can be m-dimensional. So this class let you create arbitrary R^n => R^m functions by interpolation of given (scattered) data points. Additionally, you can query the jacobi matrix of the interpolant at any query point.
Interpolation is based on triangulation, linear within each triangulation simplex and "nan" outside the convex hull.
It's less efficient than ScatteredInterpolant, but the latter supports 2-D and 3-D data only, so i made this one.
