Properly forward constructor to CopyOrReference members.
requested to merge feature/proper-generic-copyOrReference-in-BoxConstrainedQuadraticFunctional into master
The previous constructor probably was an artifact of a previous implementation and IMHO defies the benefits of the CopyOrReference class and the related ability to set its arguments on template instantiation.
This implementation complies with the constructor argument forwarding used in the base class QuadraticFunctional.
Thanks to @podlesny for pointing this out.
