HTL request attributes

HTL request attributes
While using <data-sly-include/> and <data-sly-resource/> it is now easy to pass 'requestAttributes'. These 'requestAttributes' can be accessed or processed in receiving HTL-script.

For eg.
<sly data-sly-use.settings="com.adobe.examples.htl.core.hashmap.Settings" data-sly-include="${ 'productdetails.html' @ requestAttributes=settings.settings}" />

And 'requestAttributes' can be passed from Java class.

public class Settings extends WCMUsePojo {

  // used to pass is requestAttributes to data-sly-resource
  public Map<String, Object> settings = new HashMap<String, Object>();

  @Override
  public void activate() throws Exception {
    settings.put("order", "ascending");
  }
}

Using requestAttributes using Sling-Model way.

@Model(adaptables=SlingHttpServletRequest.class)
public class ProductSettings {
  @Inject @Optional @Default(values="empty")
  public String order;

}

here 'order' is injected via the Map from the Use-class:
