Added some notes on Chip 8
Added in ISA to notes.
Added some extra notes.

And a few other things for the emulator
Added some extra files.

Two sample chip 8 programs, a glade interface (with testing code),
and a program to perform a hex dump.
Code emulator now reads in files.

It just dumps the hex code out to standard output.

Also, updated the notes file.
Working on
Added in decoding for `do_operation()`
Added some more functionality

Still need to work on `8___`, `D___`, `E___` `F___`.
Added some more OP codes.

Also fixes a few issues with the documentation.
Working on nastly oneliner for display.
Fixed(?) the display
Debugging Display writing code.
Still debugging the Dxyn Op code

V[y] is incrementing after the first iterration, kind of weird.
Fixed up issue with display.

It was actually a problem with properlying getting the Register ID's.
Forgot to bitshift them, feel kind of like an idiot.
More `F` series OP codes working.

Skipping 0xE series right now.
Finished up all `0xF` series except for 1.

That is the key input one, also need to work on `0xE` OP Codes,
but not quite sure on how key presses work.
Finished up `F` series op codes.

Still need to implement `E` series and get input/output working w/
GTK.
Implemented all of the OP Codes.

`Dxyn` still needs to set a register if there is a collision, will work
on that.

Next I need to add in the hardware.
Fixed up `Dxyn` OP Code to conform.

Going to add in Hardware Input/Output interfacing.
Some more cleanup before interfacing.
