If arguments are passed to a cost function that can be used to construct the functor, the latter will be instantiated by the cost function using std::make_unique to ensure exception safety. This not only avoids static analysis warnings caused by calling new but also spelling the cost functor type name multiple times. Also expand deduction guides for instantiating Dynamic(Auto|Numeric)DiffCostFunction from std::unique_ptr enabled constructor overloads. Finally, make CostFunction default move constructible and assignable but only through derived classes. This in turn allows derived classes to be movable without relying on custom implementations of corresponding operators. Change-Id: Idee8b9871d862bc9f9f8b5a8d0bedc52863e93c0
