Domible

- tweaks to element_from_object.
I didn't like the way headings read out within list items.
Also, treat empty objects like terminals, simple print statement.
I think it's a bit cleaner this way.

- WARNING - Breaking backward compatibility with this release
- changed several methods and variable names to snake case (Hey, kool aid!!)
- added element_from_object to domible.builders, including simple test script (efo.py) in tests directory
(not tied in to pytest though)
- added add_sublist to ListBuilder to address HTML/CSS issue with extra "bullet point."
(see comments in ListBuilder.py for more details)
- ran "poetry up" to update all version constraints in pyproject.toml
- updates to docs available at [github pages for the domible repo](https://joeldodson.github.io/domible/).

- kind of getting back to domible
- to use with another project, added a 'tools' module under domible
- added open_in_browser and save_to_file in tools

- wait for 0.1.4 to complete NavBuilder, want to get ListBuilder into pypi
- changed documentation to mkdocs, so easy to automate deployment of docs to github pages
- created ListBuilder to support NavBuilder
- added many, and moved some, elements to support a nav builder
- some modifications to dicli code and tablebuilder to support returning <style> and <script> elements
- updated README to explain how CSS and JavaScript will be generated by builders

- strange problem when installing domible[dicli]. pip appears to be installing dicli 0.1.0 and 0.1.1.
- adding versioning to dicli package using same version from
pyproject. let's see if that helps...

- missed adding `requests` package to `dev` group and `dicli` extra
- element reference pages on MDN appear to have changed. Updated parsing accordingly. This is for `dicli elements`
- Along with upgrading the parsing, extended the summary to include all sibling paragraphs after the h1 heading in the element reference page. Also for `dicli elements`
