// .NAME vtkAnnotationLayers - Stores a ordered collection of annotation sets
// .SECTION Description
// vtkAnnotationLayers stores a vector of annotation layers. Each layer
// may contain any number of vtkAnnotation objects. The ordering of the
// layers introduces a prioritization of annotations. Annotations in
// higher layers may obscure annotations in lower layers.
