Compute the flatness of cells.
This only produces values for quadrilaterals. It is defined as the cosine of the minimum dihedral angle formed by the planes intersecting in diagonals (to the fourth power).
This metric will be 1 for a perfectly flat quadrilateral and be lower as the quadrilateral deviates from the plane. A good quality quadrilateral will have a value in the range [0.3, 1]. Poorer quality cells having lower values down to -1, although malformed cells might have an infinite value.
Note that the value of this filter is consistent with the equivalent metric in VisIt, and it differs from the implementation in the Verdict library. The Verdict library returns 1 - value.
