docs: Create a set of tags for displaying a field label with inline help.
   Field label text is appended with a ? icon, which responds to a click
   by showing or hiding the provided help text.
  
   Sample usage:
  
     <%= tag_for_label_with_inline_help 'Relative Frequency', 'rel_frequency', 'Relative frequency of search traffic for this keyword across multiple search engines, as measured by WordTracker.' %>
  
   Yields:
  
     <label for="rel_frequency">Relative Frequency: <%= image_tag "/images/help_icon.png", :onclick => "$('rel_frequency_help').toggle();", :class => 'inline_icon' %></label><br />
     <div class="inline_help" id="rel_frequency_help" style="display: none;">
       <p>Relative frequency of search traffic for this keyword across multiple search engines, as measured by WordTracker.</p>
     </div>
