// .NAME vtkMergeColumns - merge two columns into a single column
//
// .SECTION Description
// vtkMergeColumns replaces two columns in a table with a single column
// containing data in both columns. The columns are set using
//
// SetInputArrayToProcess(0, 0, 0, vtkDataObject::FIELD_ASSOCIATION_NONE, "col1")
//
// and
//
// SetInputArrayToProcess(1, 0, 0, vtkDataObject::FIELD_ASSOCIATION_NONE, "col2")
//
// where "col1" and "col2" are the names of the columns to merge.
// The user may also specify the name of the merged column.
// The arrays must be of the same type.
// If the arrays are numeric, the values are summed in the merged column.
// If the arrays are strings, the values are concatenated. The strings are
// separated by a space if they are both nonempty.
