Roadmap 2.0

This issue regroups and provides an overview of the proposals for 2.0.
Leave a thumbs up if you like all, thumbs down if you don't like any, and a comment if it's somewhere in between.

- [ ] #11 Provide a `truncate` option that takes an instruction string as input `x chars/ words/ sentences/` or `comment` and add an ellipsis at the end `...`.
- [ ] #42 Remove the `multipleFormats` option and make that the default. Add a third format `stripped` which only removes the `outerHTML`
- [ ] #41 Enables to manually indicate the end of the excerpt tag. Variants are: ``, `` or could even have an `` too

Start by reading issues #11, #42, and #41, which this roadmap groups; no implementation file or test is named. Completion would require resolving these proposals and updating the roadmap, rather than making a single isolated edit.
