IOSS reader and improved basis-function support for vtkCellGrid
- An IOSS reader for vtkCellGrids.
- Improved vtkCellGridComputeSides filter (which can compute internal, not just external sides).
- Large basis function library for novel (H-curl/div) and quadratic interpolation (including 18- and 19-node pyramids) organized for use on CPU and GPU-based code. This adds the concept of generic "operator" functions which includes the basis and gradient of the basis but may be extended to operators such as curl and div.
- Changes to vtkCellAttribute to allow each cell type to use a different interpolant basis function and order.
- Fixed parameter-space coordinates for some cell shapes.
