  Renders a single event, given:

    * `event_name`: the name to use for the event
    * `event_data`: the event specification
    * `desired_example_name` (optional): the exact name of the examples to render.
    If `desired_example_name` is omitted we render all examples
    whose names start with the `event_name`.
    * `title` (optional): the title to display.  May contain markdown.  Defaults to
    `event_name` wrapped in a <code> element.
