*
* By default animate considers css properties, if you wanted to animate element attributes you
* should to prepend the symbol dollar to the attribute name. It's useful to animate svg elements.
*
* NOTE: The ability of animating attribute values is only available in gquery but not jquery

*
* Example:
*
* <pre class="code">
* //move the element from its original position to left:500px
* $("#foo").animate("left:'500'");

* $("table").animate("$width:'500'");
* </pre>
*
* In addition to numeric values, each property can take the strings 'show', 'hide', and 'toggle'.
* These shortcuts allow for custom hiding and showing animations that take into account the
* display type of the element. Animated properties can also be relative. If a value is supplied
* with a leading += or -= sequence of characters, then the target value is computed by adding or
* subtracting the given number from the current value of the property.
*
* Example:
*
* <pre class="code">
* //move the element from its original position to 500px to the left for 500ms and
* // change the background color of the element at the end of the animation
*
* $("#foo").animate("left:'+=500'", new Function(){

* $(e).css(CSS.BACKGROUND_COLOR.with(RGBColor.RED);
* }
* });
* </pre>
*
* The default duration of the animation is 500ms.
*
* For color css properties, values can be specified via hexadecimal or rgb or literal values.
