[NTLK] Added a page to the Einstein wiki for developers

[Steven Frank]

Just added this new page on Einstein architecture to the wiki:

https://github.com/pguyot/Einstein/wiki/Emulator-Architecture-Part-2 <https://github.com/pguyot/Einstein/wiki/Emulator-Architecture-Part-2>

My hope is this will be helpful to other would-be Einstein developers, as just reading the source by itself is a bit intimidating.

These are just notes I took while reading the source and stepping through in the debugger.  It gives a general idea of how the emulator starts up, and a basic inspection of the JIT mechanism.

This is the first time I've come close to understanding how the JIT works and may I just say, Paul, you are some sort of evil, but benevolent, wizard.

It would be great if Paul, Matthias, or anyone, could give this page a quick review for technical accuracy.

I'm still a ways from being able to help with the broader effort to speed up the emulator by chopping out MMU emulation, but every little bit helps..? Maybe?
