Keep freetext in the beginning of a release.

fixes #13 partially, a pr for cider will follow

There are a few things which are debatable (i.e. do we really need getter and setter for _headers?, the thought behind htas was that it feels a bit dirty to simply keep a list of elements, and maybe the implementation to keep the headers might change, but I am not sure if it would not be better to remove the getter/setter and readd them if needed (KISS?)).

One could look at Section.copy and consider turning it into a copyWith.

When adding a feature, I suggest starting with a (failing) test illustrating the use case(s). This way we'll have the API and the expectations set for the code changes, otherwise it's hard to speculate about the particular implementation. The next step (for me personally) would be any straightforward implementation which satisfies the test and introduces no untested lines. This command helps with coverage:

dart run coverage:format_coverage -l -c -i .coverage --report-on=lib --packages=.dart_tool/package_config.json | dart run check_coverage:check_coverage

Speaking of _headers, I don't see the need for getters and setters, let's keep it simple and have a final public property initialized as an empty list.

Merged in #16

Thanks for #16, I was away for the weekend and was about to do as I was told (i.e. add tests), and to cleanup the linter warnings I caused. Guess I got my feature easier, thank you :)
