// .NAME vtkTableToTreeFilter - Filter that converts a vtkTable to a vtkTree
//
// .SECTION Description
//
// 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.
