[Paraview] Labeling specific points in dataset

[Kit Chambers]

Thanks David/Utkarsh,

In the end the proceedure I went for to construct the labels was.

1- Use GenerateScalarIds filter to create a data array with the point IDs
2- Use MaskPoints filter to decimate the array
3- Use the DataLabel representation with the decimated array to show and 
the original IDs to draw the labels.

Thanks for you help on this.
