[vtkusers] vtkPLOT3dReader: Multiblock grid.

[Fletcher, Bob (GEAE)]

I'm using vtkPLOT3dReader to read a multiblock file. I couldn't find a way to
find out  the number of grids in the file. 

The simple fix is to add a Get macro to the Plot3DReader.h

  // Description:
  // Get the number of grids in the file.
  vtkGetMacro(NumGrids,int);


Is there a better way?
Any chance of getting this in the standard distribution? 

Bob.
