\class Registrar
\brief Registrar is a class that other classes register resources of
various kinds with. It makes a system that is much more amenable to
plugging in of new resources.

// By defining the external function and including it here, we save ourselves maintaing two lists.
// Also we save ourselves recompiling Registrar each time the classes that regiser change.
// Part of the idea is that the Registrar knows very little about the classes that
// register with it.
