'''When do I need to use VVExport and VVImport? It is often used in three scenarios:
 * 1) In the first one, it is used to combine large amounts of data in one LimeSurvey installation. Imagine that you run two similar surveys on two different machines. In order to combine the two response tables, you will have to use VVExport, VVImport, and a third-party app (e.g., spreadsheet apps) to combine your data and put it on one LimeSurvey installation.
 * 2) It may also be used to edit the response table of a survey. For small edits, you can access the response table and edit the desired answers. Still, for "macro-editing", VVExport and VVImport are recommended because a spreadsheet program can help you quickly edit dozens of responses at the same time.
 * 3) A "vv survey file" allows you to import the responses to a survey when the question/answer combinations have changed. Effectively, this allows you to add or remove questions in an active survey.
