Numerical comparison of data arrays in vtk files.

For comparison of numerical simulation results with analytical solutions or previous runs the numdiff software is a popular choice. We use VTK data formats to store simulation data and the vtkdiff tool shall provide means of numerical comparison of different data arrays similar to those available in the numdiff software.
