// help, if given, should have a property "handler", the click handler for the help button,

// If help isn't given, not help button is created.
// options, if given, can have the following properties:
// options.helpButton = { handler: yourEventHandler }
// options.strings = { italicexample: "slanted text" }
// `yourEventHandler` is the click handler for the help button.
// If `options.helpButton` isn't given, not help button is created.
// `options.strings` can have any or all of the same properties as
// `defaultStrings` above, so you can just override some string displayed
// to the user on a case-by-case basis, or translate all strings to
// a different language.
//
// For backwards compatibility reasons, the `options` argument can also
// be just the `helpButton` object, and `strings.help` can also be set via
// `helpButton.title`. This should be considered legacy.
//
// The constructed editor object has the methods:
// - getConverter() returns the markdown converter object that was passed to the constructor
// - run() actually starts the editor; should be called after all necessary plugins are registered. Calling this more than once is a no-op.
// - refreshPreview() forces the preview to be updated. This method is only available after run() was called.
