About resource management

[stereomatchingkiss]

I am totally new to game development and glad to find your tutorial, about the resource management with c++11, maybe add some notes about shared_ptr, unique_ptr and RAII could help a lot of developers, RAII has a huge impact on development efficiency and it make the codes more robust, no one like to new/delete, malloc/free all the times unless we have no choice. I haven't finished the tutorial yet, maybe you mention it somewhere.

Finished the chapter of flyweight and observer, about flyweight, I think shared_ptr could be a good use for this pattern(found some tutorials about this topic too). About observer, I think it is good to mention signal and slot too, after I learn signal and slot(from Qt, I am using Godot for game development), I never use observer. Maybe this is because I learn signal and slot first, but I never found a case when I would prefer observer over signal and slot unless the tools I am using do not support signal and slot.
