configureViews

Configure Books UI for both external and internal use. Should usually be called hand-in-hand with showLibraryInView, but the latter is not required if you don't need a full Books library view in your app.

uiHelpers is required to both provide an Activity and optionally to open fragments in the app's own view hierarchy.

This function should be called whenever the hosting activity is created. onDestroyView will be called automatically if it hasn't been called before this function.
