My Little Litterbox and Advanced C++ Macro Tutorial

Right...
I decided to let the "El Poho" name belong to my past, since I already have a name for my one manned so called studio which is "Catbox Beta" I actually came up with a more suiting name for the engine:
Litterbox
The editor will be probably named after another cat related thing (catnip? nah... it sounds more like scripting language to me).
Litterbox inherited a lot from El Poho but it allows me to go a step farther. With every iteration of my engine I learn new tricks, I find new traps I must avoid and learn to plan more and more ahead. The results of 20 or so iterations of my engine, since the day it could barely run a pong game are quite notable. Everything is so beautifully modular I can add and remove components without much hassle. The two months I played with the Valve's Source engine didn't go to waste either! I learned the power and infinite usefulness of macros, this knowledge makes me cringe every time I hear those naysayers say that Macros are bad, and that they only replace consts and inline functions! WRONG! Macros are a nifty little way of putting text in places making creation of new classes a cinch! Get ready for some learning because here comes a class about advanced use of C Macros!
