 * @class vtkAnnotateGlobalDataFilter
 * @brief filter for annotating with global / field data
 *
 * vtkAnnotateGlobalDataFilter is a filter that can be used to generate a
 * vtkTable with a string that contains the contents of a global / field data
 * array. It also supports extracting temporal field data arrays that
 * vtkExodusIIReader produces for "global-data". These are simply arrays that
 * have as many tuples are number of timesteps. The filter then extracts only
 * the tuple associated with the current time-step.
