// .NAME vtkQuadratureSchemeDictionaryGenerator
// .SECTION Description
//
// Given an unstructured grid on its input this filter generates
// for each data array in point data dictionary (ie an instance of 
// vtkInformationQuadratureSchemeDefinitionVectorKey). This filter 
// has been introduced to facilitate testing of the vtkQuadrature* 
// classes as these cannot operate with the dictionary. This class
// is for testing and should not be used for application development.
//
