LIE extrapolation improvements.
For the special case of LIE with additional fracture elements the extrapolator did take also the (unavailable) values from these fracture elements. This resulted in significant deviation (lower value) from the neighbour points.
A special case in the extrapolation routine now ignores such element values and yields better result.
Note, this is special for LIE and has no effect on other processes. In the new reference files only sigma_[xy]{2} has changed, other values passed all vtkdiff tests w/o modification.
Unused extrapolation interface was removed from LIE/HM to reduce confusion.
