      A file open/save dialog box.
  
      This is a Juce-based file dialog box; to use a native file chooser, see the
      FileChooser class.
  
      To use one of these, create it and call its show() method. e.g.
  
      @code
      {
          WildcardFileFilter wildcardFilter ("*.foo", String(), "Foo files");
  
          FileBrowserComponent browser (FileBrowserComponent::canSelectFiles,

                                        &wildcardFilter,
                                        nullptr);
  
          FileChooserDialogBox dialogBox ("Open some kind of file",
                                          "Please choose some kind of file that you want to open...",
                                          browser,
                                          false,
                                          Colours::lightgrey);
  
          if (dialogBox.show())
          {
              File selectedFile = browser.getSelectedFile (0);

                                  if they try to select a file that already exists. (This

                                  in an AUv3 is forbidden due to sandbox restrictions.
