    class FormBuilder
      #
      # Helper that renders translations fields
      # on a per-locale basis, so you can use them separately
      # in the same form and still saving them all at once
      # in the same request.
      #
      # Use it like this:
      #
      # <h1>Editing post</h1>
      #
      # <% form_for(@post) do |f| %>
      #   <%= f.error_messages %>
      #
      #   <h2>English (default locale)</h2>
      #   <p><%= f.text_field :title %></p>
      #   <p><%= f.text_field :teaser %></p>
      #   <p><%= f.text_field :body %></p>
      #
      #   <hr/>
      #
      #   <h2>Spanish translation</h2>
      #   <% f.globalize_fields_for :es do |g| %>
      #     <p><%= g.text_field :title %></p>
      #     <p><%= g.text_field :teaser %></p>
      #     <p><%= g.text_field :body %></p>
      #   <% end %>
      #
      #   <hr/>
      #
      #   <h2>French translation</h2>
      #   <% f.globalize_fields_for :fr do |g| %>
      #     <p><%= g.text_field :title %></p>
      #     <p><%= g.text_field :teaser %></p>
      #     <p><%= g.text_field :body %></p>
      #   <% end %>
