This is more functional than the QMK bare-bones default, although why
the HRM on the right are not all right-modifiers escapes me. This is
important where right-alt AKA AltGr is used for accents etc.
It was e for edge, now k for keys. Why? I'm toying with ideas
for a full Tutte Coxeter graph (30 vertices/nodes/GPIO pins,
45 edges/switches) incuding 42 keys plus a rotary encoder
(these act like three switches: clockwise, anticlockwise,
press - so 42 edges for normal keys + 3 edges for a rotary
encoder gives 42 + 3 = 45 edges) which could be named with
suffix 43ke.

Ψ Generating a new QMK keyboard directory
Ψ Created a new keyboard called tutte_coxeter_36e.
Ψ Build Command: qmk compile -kb tutte_coxeter_36e -km default.
Ψ Project Location: /Users/peterjc/repositories/qmk_firmware/keyboards/tutte_coxeter_36e.
Ψ Now update the config files to match the hardware!
❯ mv ~/repositories/qmk_firmware/keyboardstutte_coxeter_36e ~/repositories/qmk_userspace/keyboards
Note it did not want to accept hyphens, so used underscores.
Then define sparse 13x13 scanning matrix of 36 edge / 26 vertice graph,
using the RP2040 GPIO pin names.
i.e. The partial Tutte-Coxeter graph, using RP2040 GPIO pin names.
