Templates info:

• Place in /assets/javascripts/templates/
• named: myTemplates._
• look like this:

<div data-markerCat="<%= markerCat %>" id="menu-marker">
  <span class="menu-title"><%= markerCat %> markers</span>
  <ul>
    <% _.each(markerType, function(i) { %>
    <li data-type="<%= i.type %>" data-cat="<%= markerCat %>">
        <img src="<%= i.url %>" alt="<%= i.type %>" />
    </li> 
    <% }); %>
  </ul>
</div>
