/**
 * @class   vtkTableToTreeFilter
 * @brief   Filter that converts a vtkTable to a vtkTree
 *
 *
 *
 * vtkTableToTreeFilter is a filter for converting a vtkTable data structure
 * into a vtkTree datastructure.  Currently, this will convert the table into
 * a star, with each row of the table as a child of a new root node.
 * The columns of the table are passed as node fields of the tree.
