Implement Basket Auto Diff

[nmellado]

Add class looking like

    template < class P, class W, int Type,
            BASKET_TP(0), BASKET_TP(1), BASKET_TP(2), BASKET_TP(3), BASKET_TP(4), BASKET_TP(5), BASKET_TP(6), BASKET_TP(7), BASKET_TP(8), BASKET_TP(9), BASKET_TP(10), BASKET_TP(11) >
    class BasketAutoDiff
            : public Ext0<P,W, PrimitiveBase<P,W> >::template DDerType<P,W,Type,PrimitiveDer<P,W,Type,Ext11<P,W, Ext10<P,W, Ext9<P,W, Ext8<P,W, Ext7<P,W, Ext6<P,W, Ext5<P,W, Ext4<P,W, Ext3<P,W, Ext2<P,W, Ext1<P,W, Ext0<P,W, PrimitiveBase<P,W> > > > > > > > > > > > > > > {

    };
    /// usage: BasketAutoDiff<P, W, ScaleDer, OrientedSphereFit>;

In extensions, do

    template < class D, class W, int Di, typename TT>
    using DDerType = OrientedSphereDerImpl<D,W,Di,TT>;
}; //class OrientedSphereFitImpl

@azaleostu if you want to play a bit with template stuff, this issue could be a good extension to your PR #85
