Detailed Description

template<typename... ParamTypes>
class uLang::TEventRegistrar< ParamTypes >

Registration portion of an TEvent<>. Split out as a standalone class, so systems can expose direct registration functionality without exposing execution rights, like so:

 class CMySystem
 {
 public:
     using CMyEvent = TEvent<int>
     CMyEvent::Registrar& GetEvent() { return MyEvent; } // For external subscription
 private:
     CMyEvent MyEvent;
