A graphical visualisation of
[[https://en.wikipedia.org/wiki/Calkin%E2%80%93Wilf_tree][Calkin-Wilf
trees]].

Currently visualises it using a self adjusting number line, from the
smallest fraction to the largest fraction generated.  Both are always
positive.

The bound fractions are drawn in white, while all other fractions are
in red.  On any one iteration (taking any one fraction and generating
its two children fractions), the generated fractions are in blue while
the generator fraction is in green.

This was done just for fun really, but it's quite fun to see it
generate a dense number line over many iterations.
* TODOs
** TODO Multithreading
Currently single threaded.  A multithreaded implementation could have
multiple nodes generated at once, which would speed up the
implementation.

Might need to study my current implementation to see if it could be
done better.
** TODO Prettify code base
It's a big blob of code currently in the graphics portion.  Not very
pretty but it gets the job done.  Try modularisation.
** TODO Tree visualisation
Instead of a number line, how about visualising the actual tree at
work as a graph of nodes?  Maybe colouring nodes based on where it is
on the number line.
