configureViews
fun configureViews(actionBarProvider: ActionBarProvider?, uiConfiguration: BookLibraryUiConfiguration?, fragmentOpener: (Fragment) -> Unit?)
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.
fragmentOpener is used to open child fragments in fragments that have been opened externally.
This function should be called whenever the hosting activity is created.
