Resolves: #168

• [x] Added tests for changed code.
• [x] Updated documentation for changed code.

This is and attempt to improve quality. I've started it from beast_mode as a draft. I made some tests to understand the project code and it leaded to documentation and reference tests so i would be able to know how to contribute to the new parser refactoring.

@sveetch nice, thanks! What purpose does the makefile serve? Faster for you to get the project installed? I would personally add it to the gitignore.

The fixtures are looking good too. I'm still now completely satisfied with the html statements split into a list of strings, with the big print statement following, but we can revisit it.

Are you continuing to work this pr, or can I start merging it in?

Thanks!

@christopherpickering yeah the Makefile is an easy entrypoint to install and performing some tasks around project. I tend to think this is commonly easier for people to quickly manipulate a project, instead of learning poetry or to learn other commands that poetry can not manage.

Whatever, i will remove it if you are not confident with it.

About the stage of this PR, it is not totally finished, i had some few method to cover for Tag, so don't merge it now, i will see when i can finish it this week, i will get back to you on discord to talk about all of this soon.

@christopherpickering Ok i've finished the docstring and test coverage on Tag class.

Note than:

• The tests i've done is in "reference_tests" directory since they are totally different of your ones from tests/ dir. In the end it should be merged in test/ dir but for now they should live appart;
• There is many of "TODO" line which are notices about some incongruities and weird behaviors i found during coverage;
• poetry.lock and pyproject.toml have been automatically updated by poetry because of the development environment enabled, i don't know enough poetry to avoid this, whatever you can omit these file changes;

Edit: Oh yeah also, i've squash my many commits to one (for history consistency) and push forced, so you better be to remove the branch locally, fetch it and create it again.
