+How to use
+==========
+
+
+1) Inherit the module
+
+        <!-- fullscreen -->
+        <inherits name="com.github.fworks.screenfullgwt.ScreenFullGWT" />
+        
+
+2) Just call the static class methods
+
+        ScreenFull.toggleFullScreen();
+        
+Example (adding the toggle fullscreen on a button click handler:
+
+            getView().getFullscreen().addClickHandler(new ClickHandler() {
+                @Override
+                public void onClick(ClickEvent event) {
+                    ScreenFull.toggleFullScreen();
+                }
+            });
+            
+
