// .NAME vtkSimplePointsReader - Read a list of points from a file.
// .SECTION Description
// vtkSimplePointsReader is a source object that reads a list of
// points from a file.  Each point is specified by three
// floating-point values in ASCII format.  There is one point per line
// of the file.  A vertex cell is created for each point in the
// output.  This reader is meant as an example of how to write a
// reader in VTK.
