   * \brief
   * ValueWriter is a static class which writes the values of a DOFVector
   * values to an ascii file named values->name.'dat'. This output is done
   * via two leaf-traversals of values->feSpace->mesh. In the first traversal
   * the values at the vertices are printed, in the second these at the
   * interpolation points of each element. For a closer disription of the
   * output format see (...link fehlt noch)
