 SkyElement
 ===
 
 SkyElement is the framework for creating...yup...Sky Elements. It take heavy
 inspriation from [Polymer](www.polymer-project.org) and isn't very fully
 featured...yet
 
 Declaring an element
 --------
 ```HTML
-<link rel="import" href="../path/to/sky-element.sky" as="SkyElement" />
+<import src="../path/to/sky-element.sky" as="SkyElement" />
 <template>
   <my-other-element>Hello, {{ place }}</my-other-element>
 </template>
 <script>
 // SkyElement takes a single object as it's only parameter
 SkyElement({
   name: 'my-element', // required. The element's tag-name
   attached: function() {
     this.place = 'World';
   }, // optional

  Also, because there are so few built-in elements in Sky, the default behavior
  of HTMLElement with bindings is to assign to the property. e.g.
 
  ```HTML
  <my-foo bar="{{ bas }}">
  ```
 
  Will not `setAttribute` on the `my-foo`, instead it will assign to the `bar`
  property of `my-foo`. There are two exceptions to this: `class` & `style` --
  those still`setAttribute`.
