+Roo.enableFx = true;
+
+/**
+ * @class Roo.Fx
+ * <p>A class to provide basic animation and visual effects support.  <b>Note:</b> This class is automatically applied
+ * to the {@link Roo.Element} interface when included, so all effects calls should be performed via Element.
+ * Conversely, since the effects are not actually defined in Element, Roo.Fx <b>must</b> be included in order for the 
+ * Element effects to work.</p><br/>
+ *
+ * <p>It is important to note that although the Fx methods and many non-Fx Element methods support "method chaining" in that
+ * they return the Element object itself as the method return value, it is not always possible to mix the two in a single
+ * method chain.  The Fx methods use an internal effects queue so that each effect can be properly timed and sequenced.
+ * Non-Fx methods, on the other hand, have no such internal queueing and will always execute immediately.  For this reason,
+ * while it may be possible to mix certain Fx and non-Fx method calls in a single chain, it may not always provide the
+ * expected results and should be done with care.</p><br/>
+ *
+ * <p>Motion effects support 8-way anchoring, meaning that you can choose one of 8 different anchor points on the Element
+ * that will serve as either the start or end point of the animation.  Following are all of the supported anchor positions:</p>
+<pre>
+Value  Description
+-----  -----------------------------
+tl     The top left corner
+t      The center of the top edge
+tr     The top right corner
+l      The center of the left edge
+r      The center of the right edge
+bl     The bottom left corner
+b      The center of the bottom edge
+br     The bottom right corner
+</pre>
+ * <b>Although some Fx methods accept specific custom config parameters, the ones shown in the Config Options section
+ * below are common options that can be passed to any Fx method.</b>
+ * @cfg {Function} callback A function called when the effect is finished
+ * @cfg {Object} scope The scope of the effect function
+ * @cfg {String} easing A valid Easing value for the effect
+ * @cfg {String} afterCls A css class to apply after the effect
+ * @cfg {Number} duration The length of time (in seconds) that the effect should last
+ * @cfg {Boolean} remove Whether the Element should be removed from the DOM and destroyed after the effect finishes
+ * @cfg {Boolean} useDisplay Whether to use the <i>display</i> CSS property instead of <i>visibility</i> when hiding Elements (only applies to 
+ * effects that end with the element being visually hidden, ignored otherwise)
+ * @cfg {String/Object/Function} afterStyle A style specification string, e.g. "width:100px", or an object in the form {width:"100px"}, or
+ * a function which returns such a specification that will be applied to the Element after the effect finishes
+ * @cfg {Boolean} block Whether the effect should block other effects from queueing while it runs
+ * @cfg {Boolean} concurrent Whether to allow subsequently-queued effects to run at the same time as the current effect, or to ensure that they run in sequence
+ * @cfg {Boolean} stopFx Whether subsequent effects should be stopped and removed after the current effect finishes
+ */

+ * The constructor accepts the same config object as defined by {@link #addBinding}.
+ * If you bind a callback function to a KeyMap, anytime the KeyMap handles an expected key
+ * combination it will call the function with this signature (if the match is a multi-key
+ * combination the callback will still be called only once): (String key, Roo.EventObject e)
+ * A KeyMap can also handle a string representation of keys.<br />
+ * Usage:
+ <pre><code>
+// map one key by key code
+var map = new Roo.KeyMap("my-element", {
+    key: 13, // or Roo.EventObject.ENTER
+    fn: myHandler,

+
+// map multiple keys to one action by string
+var map = new Roo.KeyMap("my-element", {
+    key: "a\r\n\t",
+    fn: myHandler,
+    scope: myObject
+});
+
+// map multiple keys to multiple actions by strings and array of codes
+var map = new Roo.KeyMap("my-element", [

+ </code></pre>
+ * @cfg {String} path The path for which the cookie is active (defaults to root '/' which makes it active for all pages in the site)
+ * @cfg {Date} expires The cookie expiration date (defaults to 7 days from now)
+ * @cfg {String} domain The domain to save the cookie for.  Note that you cannot specify a different domain than
+ * your page is on, but you can specify a sub-domain, or simply the domain itself like 'roojs.com' to include
+ * all sub-domains if you need to access cookies across different sub-domains (defaults to null which uses the same
+ * domain the page is running on including the 'www' like 'www.roojs.com')
+ * @cfg {Boolean} secure True if the site is using SSL (defaults to false)
+ * @constructor
+ * Create a new CookieProvider
+ * @param {Object} config The configuration object
