/**
 * Quickly throw together greybox wireframes. Use in conjunction with other
 * inuit.css objects to create simple greybox prototypes, e.g.:
 *
   <div class="island  greybox  greybox--medium">Header</div>

   <ul class="nav  nav--fit  nav--block  greybox">
       <li><a href=#>Home</a></li>
       <li><a href=#>About</a></li>
       <li><a href=#>Portfolio</a></li>
       <li><a href=#>Contact</a></li>
   </ul>
 *
 * The beauty of combining the greyboxing with inuit.css objects is that any
 * prototyping can quickly be converted into/used as production code.
 *
 * For a more complete prototyping framework, consider Adam Whitcroft’s Proto:
