webpack模式下无法使用插件

`import iSlider from 'islider.js' import dot from 'islider.js/build/iSlider.plugin.dot.js'`
通过以上代码引入iSlider之后，插件不能使用。查了下代码，因为`build/iSlider.plugin.dot.js`文件中把插件注册到`build/iSlider.js`这个文件里了。但是iSilder引入的是`build/index.bundle.js`
希望修正一下这个问题

Start by reading build/iSlider.plugin.dot.js and comparing its registration target with the webpack entry represented by build/index.bundle.js. Reproduce the import shown in the issue, then verify that the dot plugin is usable after importing iSlider through the webpack build.
