/**
 * Provides a convenient method of performing basic date arithmetic.  This method

 * a new Date instance containing the resulting date value.
 *
 * Examples:
 * <pre><code>
//Basic usage:
var dt = new Date('10/29/2006').add(Date.DAY, 5);
document.write(dt); //returns 'Fri Oct 06 2006 00:00:00'

//Negative values will subtract correctly:
var dt2 = new Date('10/1/2006').add(Date.DAY, -5);
document.write(dt2); //returns 'Tue Sep 26 2006 00:00:00'

//You can even chain several calls together in one line!
var dt3 = new Date('10/1/2006').add(Date.DAY, 5).add(Date.HOUR, 8).add(Date.MINUTE, -30);
document.write(dt3); //returns 'Fri Oct 06 2006 07:30:00'

 * @param {Number} value      The amount to add to the current date
 * @return {Date} The new Date instance

/**
 * @class Roo.DomQuery
Provides high performance selector/xpath processing by compiling queries into reusable functions. New pseudo classes and matchers can be plugged. It works on HTML and XML documents (if a content node is passed in).
<p>
DomQuery supports most of the <a href="http://www.w3.org/TR/2005/WD-css3-selectors-20051215/">CSS3 selectors spec</a>, along with some custom selectors and basic XPath.</p>

<p>
All selectors, attribute filters and pseudos below can be combined infinitely in any order. For example "div.foo:nth-child(odd)[@foo=bar].bar:first" would be a perfectly valid selector. Node filters are processed in the order in which they appear, which allows you to optimize your queries for your document structure.
</p>
<h4>Element Selectors:</h4>
<ul class="list">
    <li> <b>*</b> any element</li>
    <li> <b>E</b> an element with the tag E</li>
    <li> <b>E F</b> All descendent elements of E that have the tag F</li>
    <li> <b>E > F</b> or <b>E/F</b> all direct children elements of E that have the tag F</li>
    <li> <b>E + F</b> all elements with the tag F that are immediately preceded by an element with the tag E</li>
    <li> <b>E ~ F</b> all elements with the tag F that are preceded by a sibling element with the tag E</li>
</ul>
<h4>Attribute Selectors:</h4>
<p>The use of @ and quotes are optional. For example, div[@foo='bar'] is also a valid attribute selector.</p>
<ul class="list">
    <li> <b>E[foo]</b> has an attribute "foo"</li>
    <li> <b>E[foo=bar]</b> has an attribute "foo" that equals "bar"</li>
    <li> <b>E[foo^=bar]</b> has an attribute "foo" that starts with "bar"</li>
    <li> <b>E[foo$=bar]</b> has an attribute "foo" that ends with "bar"</li>
    <li> <b>E[foo*=bar]</b> has an attribute "foo" that contains the substring "bar"</li>
    <li> <b>E[foo%=2]</b> has an attribute "foo" that is evenly divisible by 2</li>
    <li> <b>E[foo!=bar]</b> has an attribute "foo" that does not equal "bar"</li>
</ul>
<h4>Pseudo Classes:</h4>
<ul class="list">
    <li> <b>E:first-child</b> E is the first child of its parent</li>
    <li> <b>E:last-child</b> E is the last child of its parent</li>
    <li> <b>E:nth-child(<i>n</i>)</b> E is the <i>n</i>th child of its parent (1 based as per the spec)</li>
    <li> <b>E:nth-child(odd)</b> E is an odd child of its parent</li>
    <li> <b>E:nth-child(even)</b> E is an even child of its parent</li>
    <li> <b>E:only-child</b> E is the only child of its parent</li>
    <li> <b>E:checked</b> E is an element that is has a checked attribute that is true (e.g. a radio or checkbox) </li>
    <li> <b>E:first</b> the first E in the resultset</li>
    <li> <b>E:last</b> the last E in the resultset</li>
    <li> <b>E:nth(<i>n</i>)</b> the <i>n</i>th E in the resultset (1 based)</li>
    <li> <b>E:odd</b> shortcut for :nth-child(odd)</li>
    <li> <b>E:even</b> shortcut for :nth-child(even)</li>
    <li> <b>E:contains(foo)</b> E's innerHTML contains the substring "foo"</li>
    <li> <b>E:nodeValue(foo)</b> E contains a textNode with a nodeValue that equals "foo"</li>
    <li> <b>E:not(S)</b> an E element that does not match simple selector S</li>
    <li> <b>E:has(S)</b> an E element that has a descendent that matches simple selector S</li>
    <li> <b>E:next(S)</b> an E element whose next sibling matches simple selector S</li>
    <li> <b>E:prev(S)</b> an E element whose previous sibling matches simple selector S</li>
</ul>
<h4>CSS Value Selectors:</h4>
<ul class="list">
    <li> <b>E{display=none}</b> css value "display" that equals "none"</li>
    <li> <b>E{display^=none}</b> css value "display" that starts with "none"</li>
    <li> <b>E{display$=none}</b> css value "display" that ends with "none"</li>
    <li> <b>E{display*=none}</b> css value "display" that contains the substring "none"</li>
    <li> <b>E{display%=2}</b> css value "display" that is evenly divisible by 2</li>
    <li> <b>E{display!=none}</b> css value "display" that does not equal "none"</li>

     * <b>Combining Options</b><br>
     * Using the options argument, it is possible to combine different types of listeners:<br>
     * <br>
     * A normalized, delayed, one-time listener that auto stops the event and passes a custom argument (forumId)<div style="margin: 5px 20px 20px;">
     * Code:<pre><code>
el.on('click', this.onClick, this, {
    single: true,
    delay: 100,
    stopEvent : true,
    forumId: 4
});</code></pre>
     * <p>
     * <b>Attaching multiple handlers in 1 call</b><br>
      * The method also allows for a single argument to be passed which is a config object containing properties
     * which specify multiple handlers.
     * <p>
     * Code:<pre><code>
el.on({
    'click' : {
        fn: this.onClick
        scope: this,
        delay: 100

 * <b>Animations</b><br />
 * Many of the functions for manipulating an element have an optional "animate" parameter. The animate parameter
 * should either be a boolean (true) or an object literal with animation options. The animation options are:
<pre>
Option    Default   Description
--------- --------  ---------------------------------------------
duration  .35       The duration of the animation in seconds
easing    easeOut   The YUI easing method
callback  none      A function to execute when the anim completes
scope     this      The scope (this) of the callback function
</pre>
* Also, the Anim object being used for the animation will be set on your options object as "anim", which allows you to stop or
* manipulate the animation. Here's an example:
<pre><code>
var el = Roo.get("my-div");

// no animation
el.setWidth(100);

// default animation
el.setWidth(100, true);

// animation with some options set
el.setWidth(100, {
    duration: 1,
    callback: this.foo,
    scope: this
});

// using the "anim" property to get the Anim object
var opt = {
    duration: 1,
    callback: this.foo,
    scope: this
};
el.setWidth(100, opt);
...
if(opt.anim.isAnimated()){
    opt.anim.stop();
}
