* Created by Allan Wang on 2017-06-28.
*
* Floating About Activity Panel for your app
* This contains all the necessary layouts, and can be extended and configured using [buildConfigs]
* The [rClass] is necessary to generate the list of libraries used in your app, and should point to your app's
* R.string::class.java
* If you don't need auto detect, you can pass null instead
* Note that for the auto detection to work, the R fields must be excluded from Proguard
* Manual lib listings and other extra modifications can be done so by overriding the open functions
