refactor
introduce a sensing style test, want to find the width and height of the area
make the first bit of the test 'pass'
the tests pass, but I know they really fail
further validation
remove unneeded code
verification of sanity check
reformat
move things around
hurrah, something fails for reasons I dont understand
use internal assertions to document behaviour
store details
does it export to a png
require fs
leaev a failing test for when I am not tipsy
