-    This is similar to a button, but appears like a link instead. It's generally
-    for non-destructive actions and should never navigate the page.
-
-    ex. <a is="cr-action" on-tap="{{ doSomething }}"></a>
-
-    Note: This element is very common on typical pages so it's been micro
-    optimized to not contain any whitespace and not use data binding in the
-    template.
