+ * 这里提供一个工厂方法，用于生产一个popup插件配置，或基于popup特性实现自己的插件
+ * @param {Object} optons 针对popup扩展了定制化参数，另外也用来重写部分PluginConfig配置
+ * @param {String} optons.name 插件名
+ * @param {String} optons.tagName Popup DOM容器的tagName
+ * @param {String} optons.className Popup DOM容器的className
+ * @param {String} optons.title Popup 标题，当设置值为 false 则不渲染title对应DOM
+ * @param {String} optons.body Popup 内容，当设置值为 false 则不渲染body对应DOM
+ * @param {String} optons.html html 用于构架popup的模板，重写后上面的title、body无效
+ * @param {String} optons.offset 设定相对播放器要展示的坐标位置，空格分割的坐标值：'X:left Y:top'||'top right bottom left', 具体的像素百分比值或者auto；实例化后可重写 popupplugin.offset('0 0 0 0')
+ * @param {String} optons.offsetAttr offset对应的CSS属性key，默认'left top'、'top right bottom left'-当offset空格分割的参数值多余2个时，便于只设定个别或特定方向边距
+ * @param {String} optons.translate 在offset基础上的偏移量，格式如："leftVal topVal"，当offset为50%这里没设定值，则默认偏移-50%；实例化后可重写 popupplugin.translate('0 0')
+ * @param {String} optons.width 宽度值（需要带单位）；实例化后可重写 popupplugin.width('100px')
+ * @param {String} optons.height 高度值（需要带单位）；实例化后可重写 popupplugin.height('100px')
+ * @param {Boolean} optons.hide 初始状态是否设置为关闭，默认值 false
+ * @param {Function} optons.opened 开启时执行
+ * @param {Function} optons.closed 关闭时执行
+ * @param {Boolean} optons.penetrate 是否将交互事件同步到video元素(点击当前popup同样实现video的暂停播放)，默认值 false
+ * @param {Boolean} optons.operable 是否启用事件交互（false则设置CSS事件穿透），默认值 true

+ * @param {String} optons.title Popup 标题，当设置值为 false 则不渲染title对应DOM

+ * @param {String} optons.html html 用于构架popup的模板，重写后上面的title、body无效
+ * @param {String} optons.offset 设定相对播放器要展示的坐标位置，空格分割的坐标值：'X:left Y:top'||'top right bottom left', 具体的像素百分比值或者auto；实例化后可重写 popupplugin.offset('0 0 0 0')
+ * @param {String} optons.offsetAttr offset对应的CSS属性key，默认'left top'、'top right bottom left'-当offset空格分割的参数值多余2个时，便于只设定个别或特定方向边距
+ * @param {String} optons.translate 在offset基础上的偏移量，格式如："leftVal topVal"，当offset为50%这里没设定值，则默认偏移-50%；实例化后可重写 popupplugin.translate('0 0')

+ * @param {String} optons.height 高度值（需要带单位）；实例化后可重写 popupplugin.height('100px')
+ * @param {Boolean} optons.hide 初始状态是否设置为关闭，默认值 false
+ * @param {Function} optons.opened 开启时执行
+ * @param {Function} optons.closed 关闭时执行
+ * @param {Boolean} optons.penetrate 是否将交互事件同步到video元素(点击当前popup同样实现video的暂停播放)，默认值 false
+ * @param {Boolean} optons.operable 是否启用事件交互（false则设置CSS事件穿透），默认值 true
