Registry class maintaining the mapping of `https://developer.android.com/reference/kotlin/androidx/leanback/widget/Row` subclasses to `https://developer.android.com/reference/kotlin/androidx/leanback/app/BrowseFragment.FragmentFactory`. BrowseRowFragment automatically registers `https://developer.android.com/reference/kotlin/androidx/leanback/app/BrowseFragment.ListRowFragmentFactory` for handling `https://developer.android.com/reference/kotlin/androidx/leanback/widget/ListRow`. Developers can override that and also if they want to use custom fragment, they can register a custom `https://developer.android.com/reference/kotlin/androidx/leanback/app/BrowseFragment.FragmentFactory` against `https://developer.android.com/reference/kotlin/androidx/leanback/widget/PageRow`.
