NonCopyable base class so you can inherit instead of implementing in every class

NonCopyable.h

#pragma once

class NonCopyable
{	
protected:
	// 1. provide default ctor so it doesn't have to be explicitly defined in inherited classes
	// 2. make NonCopyable class abstract so it can't be instantiated
	NonCopyable() {}
	/*virtual*/ ~NonCopyable() {}

private:
	// no copy construction
	NonCopyable(const NonCopyable&) {}
	// no copy by operator=
	NonCopyable& operator=(const NonCopyable&) {}

};
