* @class vtkBoundedPointSource
* @brief create a random cloud of points within a
* specified bounding box
*
*
* vtkBoundedPointSource is a source object that creates a user-specified
* number of points within a specified bounding box. The points are scattered
* randomly throughout the box. Optionally, the user can produce a
* vtkPolyVertex cell as well as random scalar values within a specified
* range. The class is typically used for debugging and testing, as well as
* seeding streamlines.
