Usage

Add widget in your xml layout like this:

    <ru.github.igla.ferriswheel.FerrisWheelView
        android:id="@+id/ferrisWheelView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center"
        app:fwv_cabinsNumber="8"
