* update matrix.c

* make the matrix representation of the layout macro

* fix up LAYOUT macro

* add missing character

* initial keymap commit

* put KC_NO where they belong

* basic keymap

* clean up the file a little

* use LAYOUT_96_ansi

* add a second layer for lighting controls

* add in lighting support

* add QMK Configurator support

* use pragma once

* remove un needed matrix.c

* convert to GPIO methods

* turn on rgblight_enable and get rid of custom matrix

* set bootloadhid_bootloader to 1

* set bootmagic to lite and set it to k50

* add reset information to readme

* use i2c_master instead of custom i2c

* restore the custom i2c code

* introduce reset key and eep_rst in function layer 1

* fix up pip3 install commands

* fix up device and manufacturer names

* remove un needed comments

* add an ALL layout macro along with QMK Configurator support
