Avoid indirection caused by passing shared_ptr by reference The block factory does not have responsability on the lifetime of their inputs Define std::make_unique when using C++11 and make use of it Printers are turned into unique_ptr to express ownership Printers do not participate on the lifelime of the data, so they take const raw pointers Modernize tests code
