[vtkusers] instances of vtkQuad in vtkStructuredGrid

A structured grid is defined implicitly: that is, by the specification of 
dimensions, e.g., 10x20x30. If the dimensions indicate a 3D grid then the 
cells are implicitly  hexahedron. If the dimensions are 2D (e.g., 10x20x1) 
then the cells are implicitly quadrilaterals. You don't insert cells 
directly: just dimensions and points.
