6d81bc8b06
Adds a variable `GlobalPointIndexStart` to `CellSetStructured`. Adding this to the cell-set, instead of the coordinate system, enables this feature for different types of datasets like uniform grid, rectilinear, etc., with this one change. The extents can be computed using `GlobalPointIndexStart` and `PointDimensions`.
