Return the proper const reference type of a given type.
For instance: const_ref<float>::value_t == const float& const_ref<argument_t>::value_t == const_argument_ref
This returns a const Eigen::Ref for dense Eigen matrices, else a simple const reference.
Note: this currently does not cover all cases (e.g. sparse vectors), but should work for argument_t/vector_t (dense vectors).
