[vtkusers] conversion of image data to unstructured grid

[Amy Squillacote]

Hi Martin,

vtkStructuredPointsToUnstructuredGridFilter is an abstract class. Before 
the new pipeline in VTK (i.e., version 4.4 and earlier), it was the 
superclass for filters that took vtkStructuredPoints as input and 
produced vtkUnstructuredGrid as output. In VTK 5.*, the superclass for 
filters that produce vtkUnstructuredGrid is 
vtkUnstructuredGridAlgorithm. vtkDataSetTriangleFilter is one of its 
subclasses that operates on any vtkDataSet and produces 
vtkUnstructuredGrid. See 
http://www.vtk.org/doc/nightly/html/classvtkDataSetTriangleFilter.html.
