// .NAME vtkStrangeAttractors - Read points from a Tipsy standard binary file
// .SECTION Description
// Read points from a Tipsy standard binary file. Fully parallel. Has ability
// to read in additional attributes from an ascii file, and to only load in
// marked particles but both these functions are serial only.
