<dt>应用说明：</dt>
<dd>* 必须对包裹子元素的直接父元素应用该方法
<dd>* example:
<pre>
$("#picturewrap").rollGallery({
direction:"top",
speed:2000,
showNum:4,
aniMethod:"easeOutCirc"
});
</pre>
</dd>
<dd>* direction：移动方向。可取值为："left" "top"</dd>
<dd>* speed：速度。单位毫秒</dd>
<dd>* noStep：设置为：true 则按非步进方式滚动。非步进下动画效果失效。</dd>
<dd>* speedPx：非步进滚动下的移动速度。单位像素</dd>
<dd>* showNum：显示个数。即父元素能容纳的子元素个数</dd>
<dd>* rollNum：一次滚动的个数。注意总个数必须为rollNum的倍数！</dd>
<dd>* aniSpeed：动画速度</dd>
<dd>* aniMethod：动画方法（需插件（如：easing）支持）</dd>
<dd>* childrenSel：子元素筛选器</dd>
