* move gh-badges files out of /lib
As far as possible, this is just moving files
around and updating paths however there are 2
functional changes in this commit:
- remove use of lib/register-chai-plugins.spec
in badge-cli.spec.js
- remove use of starRating()
in text-measurer.spec.js
* update service tests that use colorscheme.json
* split package.json in two
* clean up import
* don't hard-code path
* start a changelog
* put a license file in the package dir
* re-organise documentation 📚
* don't pack test files
* remove favicon from Makefile
* give package its own test command
* link the docs better in README
Reorg of the tests: move them just alongside their code. The principle relates to grouping by coupling, not by function and is established in best-practice documents (e.g. https://github.com/focusaurus/express_code_structure#underlying-principles-and-motivations), despite its break from the tradition of a separate `test/` tree. All of today's tools can handle tests spread through the repository.
There are some good, if subtle consequences of this change:
- Since files are close at hand, friction is reduced at development time, which encourages that new tests are written to cover new behaviors.
- It's easier to find the tests that cover a particular piece of functionality.
- It's easier to see which code has tests and which doesn't.
