i'll add tests and docs later today

@ikitommi the tests you added yesterday aren't passing in master

never mind that

the git merge produced some weird hanging diffs

they pass all right

should it treat an empty request-method as GET or as not-GET?

added tests and docs

pushed out [metosin/reitit "0.2.5"] with the new slash-handler for reitit-ring & reitit-http, thanks @vale! the docs: https://cljdoc.org/d/metosin/reitit/0.2.5/doc/ring/slash-handler
