Comment (by hinder):

 Interpolation within Carpet (i.e. for prolongation, which is separate from
 that provided by AEILocalInterp) is tested using a polynomial for which
 interpolation of the correct order (at least for some interpolators) is
 exact.  This means that the correct solution is trivial and it's obvious
 if the test is correct or not.  I propose some sort of initial data thorn
 for setting polynomial initial data which could be used by the testsuites
 for the interpolator.  This would be part of Cactus, as it is sufficiently
 generic and useful for testing interpolator thorns.  I don't think we
 should use an Einstein-based initial data thorn for testing the
 interpolators.  This belongs in Cactus, not the ET.
