It is better to start with what a class does than what it does not.

/**
- * A DataOut-like class that does not output a numerical solution on
- * the cells of the original triangulation but interpolates the result onto a
- * second triangulation (that can be completely unrelated).
- * By using this class, one can output the result obtained on an unstructured
- * mesh onto a structured one or one can create a slice in 3D.

In the beginning the Universe was created. This has made a lot of
people very angry and has been widely regarded as a bad move.
