/// The variations filter dialog displays several columns
/// with the different types of variations shown as checkboxes.
/// This is used to filter the variations that are shown in the main window
/// because the list is very long.
/// The results are stored in a map and returned.
/// These are used in conjunction with the filter edit box to filter what's shown.
