Provide documentation for API methods exposed through Google Cloud Endpoints
<p>How can I document each cloud endpoints APIs? For example I have the following code. I can write an overview for <code>FooApi</code> with <code>@Api</code> annotation. However I want to write a doc for the method <code>getSomething</code> here. Is there any annotation?</p>

<pre><code>@Api(name = "foo", version = "v1", description = "this api...")
public class FooApi {
  // I want to write a description for this specific method
  @ApiMethod(httpMethod = "get")
  public Bar getSomething() {
  }
}
</code></pre>
