// .NAME vtkMRMLAnnotationTextNode - MRML node to represent a text.
// .SECTION Description
// Annotation nodes contains control points, internally represented as vtkPolyData.
// A Annotation node contains many control points  and forms the smallest logical unit of tractography
// that MRML will manage/read/write. Each control point has accompanying data.
// Visualization parameters for these nodes are controlled by the vtkMRMLAnnotationPointDisplayNode class.
