This debugging script assists in the progress that is neccessary after
stylesheet updates: It runs the html regression test to dump generated HTMLs to
the hard disk, generates canonicalized and formatted versions of them, and
allows you to compare the committed versions with the newly generated ones.

Canonicalized, formatted HTML test files have been generated in subdirectories
of target/diffable-html:
 - old: As present in src/test/resources/*.html
 - new: As generated from the current version of the stylesheet
 - new-raw: Not canonicalized and formatted, i.e. ready for inclusion in the next commit.
