I have some questions.

Why would you rather do this than include the additional stylesheet in your app/assets/stylesheets/application.css?

Assuming we still want this feature, I think we should make it more generic and allow overriding all CSS, i.e. default it to the built-in CSS. I propose that we name this stylesheet_paths and make it an Array.

GrapeSwaggerRails.options.stylesheet_paths << 'some.css' # [ 'grape_swagger_rails/application.css', 'some.css' ]

Then

  <% GrapeSwaggerRails.options.stylesheet_paths.each do |stylesheet_path| %>
    <%= stylesheet_link_tag stylesheet_path %>
  <% end %> 

To be merged this needs tests, too, please.

If you really want to be ambitious, users should also be able to configure script_paths, i.e. all the JS.
