// .NAME vtkMergeFields - Merge multiple fields into one.
// .SECTION Description
// vtkMergeFields is used to merge mutliple field into one.
// The new field is put in the same field data as the original field.
// For example
// @verbatim
// mf->SetOutputField("foo", vtkMergeFields::POINT_DATA);
// mf->SetNumberOfComponents(2);
// mf->Merge(0, "array1", 1);
// mf->Merge(1, "array2", 0);
// @endverbatim
// will tell vtkMergeFields to use the 2nd component of array1 and
// the 1st component of array2 to create a 2 component field called foo.
// The same can be done using Tcl:
// @verbatim
// mf SetOutputField foo POINT_DATA
// mf Merge 0 array1 1
// mf Merge 1 array2 0
//
// Field locations: DATA_OBJECT, POINT_DATA, CELL_DATA
// @endverbatim
