#define N

Instantiate a registry class.

This provides template definitions of add_node, begin, and the Head and Tail pointers, then explicitly instantiates them. We could explicitly specialize them, instead of the two-step process of define then instantiate, but strictly speaking that's not allowed by the C++ standard (we would need to have explicit specialization declarations in all translation units where the specialization is used) so we don't.
