Apart from adding a test case for vtkTriQuadraticPyramid in
quadraticEvaluation, a lot of initializations are now using `auto`.
Additionally, raw pointers have been replaced with vtkSmartPointers.
Lastly, the weights of the quadraticPyramid are now corrected to be
13 instead of 20. Also use the same datasets as in quadraticIntersection
for consistency.
