Appears to be proper index conversion from node to points.
Interpret Isatis nodes at VTK_CELL types

Isatis nodes are gravity-centered nodes, which correspond to VTK_CELL.
Previous implementation as interpreting 'nodes' to mean VTK_POINT.
Specified ISATISReaderDelegate::createPoints for vtkStructured Grids.

The original design of the ISATISReaderDelegate class passed data by
using vtkPointSet, which is a parent class to things such as
vtkStructuredGrid, vtkUnstructuredGrid, etc. This worked when the Isatis
data was being interpreted as points, because then it was a simple 1-1
transfer of Isatis coordinate info arrays into a vtkPoints object.

Now that the Isatis data is being interpreted as cells, this isn't a
simple 1-1 transfer anymore because there are more VTK_POINTS than there
are Isatis coordinates. The furthest boundary planes have to be
manufactured, plus every coordinate has to be shifted by half-deltas.

Enough information was sent to make this specific for vtkStructuredGrid.
Concurrent pt-based, cell-based indexing.

Most of the work is inside createPoints, the Isatis data needs to be
accessed based on the cell count while the vtkStructuredGrid needs to
be accessed based on the point count. This differ significantly and get
increasingly out of sync.
