ReactInstanceManager (ReactAndroid 0.12.0 API)

```
public class ReactInstanceManager
extends java.lang.Object
```
This class is managing instances of CatalystInstance. It expose a way to configure catalyst instance using ReactPackage and keeps track of the lifecycle of that instance. It also sets up connection between the instance and developers support functionality of the framework. An instance of this manager is required to start JS application in ReactRootView (see ReactRootView.startReactApplication(com.facebook.react.ReactInstanceManager, java.lang.String) for more info). The lifecycle of the instance of ReactInstanceManager should be bound to the activity that owns the ReactRootView that is used to render react application using this instance manager (see ReactRootView.startReactApplication(com.facebook.react.ReactInstanceManager, java.lang.String)). It's required to pass owning activity's lifecycle events to the instance manager (see onPause(), onDestroy() and onResume(com.facebook.react.modules.core.DefaultHardwareBackBtnHandler)). To instantiate an instance of this class use builder().
