message:
   Add option for allowing extrapolation during interpolation. This
   situation may arise during mesh refinement as a result of round-off
   errors. New mesh points may be added that are slightly misplaced and
   happen to lie outside the domain.

   If the global option "allow_extrapolation" is set, then the closest
   cell is found and the values extrapolated from there. In such cases, a
   warning is issued and the maximum distance to the original mesh is
   reported.
