Variation on Observer pattern, using C++11 move/copy

	/*
	Variation on the Observer design pattern.

	I just want to keep a list of items, and call methods on them. (Similar to observer's notify)
	But the items will always be in a list (ie, automatic registration)

	Instead of the items requiring to be inside pointers or pointer wrappers, this handles stack allocated
	items too, and items inside std containers, using copy and move semantics.

	Uses C++11 features, compile with gcc -std=c++11 or equivalent
