* Having the header files in a seperate dir is only useful when developing libraries that are meant to be used by other programs. In our case though it makes the file structure more tedious so gather everything in one place.

In addition: * Correct register notation (word refers to a 32bit quantity not 16bit) * Simplify sign extension casing * Add more useful logging

* This commit adds a most basic CPU class that acts as a template which we will slowly build. * The architecture is pretty simple; the ComponentManager will create all the seperate components (EE, VP, IOP, GS etc) as unique_ptr's since it owns them and only it has access to them. All the other components must pass through the manager to read/write data to memory. To achieve this they are given a pointer to the ComponentManger in their constructor. * For now the CPU directly accesses the bios which shouldn't happen but will be fixed eventually when I implement generic read/writes. The goal is to start implementing the CPU as fast as possible in order to get to the GPU/VPU's and display something!

* This is the beginning of a surely arduous journey of semi-correctly emulating the PS2 the flagship console from Sony in 2001. The console was chosen for it's impressive performance at the time, relatively simple MIPS architecture compared to the PowerPC (Gamecube) and x86 (Xbox) competitors at the time, and because I own one since I wouldn't want to be caught doing piracy on an open source competition... The PS2 also has a myriad of resources available including comprehensive CPU documentation for it's MIPS ISA which will be used in the development of this emulator. Any sources that I use, will be referenced in the coresponding commits for the judges to look at. For development hardware documentation and info from real emulators will be used (I'll try to avoid using code from other projects as much as possible though). I've also done a PS1 emulator in the past so the minor similarities in architecture will help speed this process up a little. For now this is just a window with glfw and a ready opengl context. I hope it will be able to boot the PS2 soon enough though...
