/**
* @class vtkGenericPointIterator
* @brief iterator used to traverse points
*
* This class (and subclasses) are used to iterate over points. Use it
* only in conjunction with vtkGenericDataSet (i.e., the adaptor framework).
*
* Typical use is:
* <pre>
* vtkGenericDataSet *dataset;
* vtkGenericPointIterator *it = dataset->NewPointIterator();
* for (it->Begin(); !it->IsAtEnd(); it->Next());
* {
* x=it->GetPosition();
* }
* </pre>
