[doc][xs]: formatting for doc head.
[test][xs]: remove accidentially added and broken test.
[#75,wizard][m]: start on heavy refactor to be a proper "wizard".

* current wizard was just you inputing in your own url string
* started splitting into separate inputs - one for url, one for head (as an example)
* iframe results directly from datapipes rather than js + exec method
* improvements are only partial - lots to do - see issue #75
