工具的编辑框内可编写代码然后运行；代码内可调用本工具提供的Runtime的方法，使用了这些方法时，如果要copy代码到其他html内使用，需要把Runtime相关的调用删除或使用别的代码代替。
可调用Runtime方法列表：
RootFolder:"" 当前程序根目录，结尾不含/
Runtime.Import(jsList) 导入js列表，只能调用一次，jsList:[{url:"",check:fn()},...] check返回false跳过这条的导入
Runtime.Ctrls(ctrls) 在控制区显示按钮，只能调用一次，ctrls:[{name:"按钮名称",click:"函数名称",cls:"class name"},{html:"html代码"},{choiceFile:{multiple:true,name:"音乐",title:"转换",mime:"audio/*",process:fn(fileName,arrayBuffer,filesCount,fileIdx,endCall)}},...]
Runtime.DecodeAudio(fileName,arrayBuffer,True,False) 解码一个音频文件，True({sampleRate:采样率,duration:音频时长,srcBlob:Blob对象,type:从文件名中提取的音频类型,data:[Int16,...]pcm数据})，False(errMsg)
