Once again I left out a detail - the reason I have the span is that I
want to apply a CSS class to the star. Also, I like to have the star
as a child of the other component, because that way I don't have to
assign unique names to each star, and also, I can package the text and
the star as one object type (or just use a single method to deal with
both at once) so that I don't have duplicated code.
