class_docstr: Create most of a 3 or 4 row, 3 column search dialog.
  
  The left and wide middle column contain:
  1 or 2 labeled text entry lines (make_entry, create_entries);
  a row of standard Checkbuttons (make_frame, create_option_buttons),
  each of which corresponds to a search engine Variable;
  a row of dialog-specific Check/Radiobuttons (create_other_buttons).
  
  The narrow right column contains command buttons
  (make_button, create_command_buttons).
  These are bound to functions that execute the command.
  
  Except for command buttons, this base class is not limited to items
  common to all three subclasses.  Rather, it is the Find dialog minus
  the "Find Next" command, its execution function, and the
  default_command attribute needed in create_widgets. The other
  dialogs override attributes and methods, the latter to replace and
  add widgets.

docstr: Return (filled frame, options) for testing.
  
  Options is a list of searchengine booleanvar, label pairs.
  A gridded frame from make_frame is filled with a Checkbutton
  for each pair, bound to the var, with the corresponding label.
