This header contains a null_deleter implementation. This is an empty function object that receives a pointer and does nothing with it. Such empty deletion strategy may be convenient, for example, when constructing shared_ptrs that point to some object that should not be deleted (i.e. a variable on the stack or some global singleton, like std::cout).
