[vtkusers] Threads, MultiCore and VTK

[John Norris]

Regarding #3, I created an abstract class vtkMultiGroupThreadedAlgorithm 
that automates multithreading, including intelligent handling of 
ProgressEvents (but not vtk[Debug|Warning|Error]Macros).  It works well, 
but I haven't done any kind of performance testing.  Also it only works 
on composite datasets, as you might guess from the name.
