/**
* 插入html代码
* @command inserthtml
* @method execCommand
* @param { String } cmd 命令字符串
* @param { String } html 插入的html字符串
* @remaind 插入的标签内容是在当前的选区位置上插入，如果当前是闭合状态，那直接插入内容， 如果当前是选中状态，将先清除当前选中内容后，再做插入
* @warning 注意:该命令会对当前选区的位置，对插入的内容进行过滤转换处理。 过滤的规则遵循html语意化的原则。
* @example
* ```javascript
* //xxx[BB]xxx 当前选区为非闭合选区，选中BB这两个文本
* //执行命令，插入<b>CC</b>
* //插入后的效果 xxx<b>CC</b>xxx
* //<p>xx|xxx</p> 当前选区为闭合状态
* //插入<p>CC</p>
* //结果 <p>xx</p><p>CC</p><p>xxx</p>
* //<p>xxxx</p>|</p>xxx</p> 当前选区在两个p标签之间
* //插入 xxxx
* //结果 <p>xxxx</p><p>xxxx</p></p>xxx</p>
* ```
