Also adds implicit conversion configuration option to Type constructor,
and institutes a numbers-only bundle, and supports argument matching
with implicit conversions.
Still need to test that a behavior that invokes implicit conversion ends up
with the conversion operation as a dependency (and so regenerates itself if
the conversion changes).
We use [mocha](https://mochajs.org/) as the test framework, as it is
the tool used by mathjs and we would like to make tests as similar
as possible. However, to tighten the linkage between source code and
tests, we adopt a somewhat different file organization: unit tests
for a given source file `blah/foo.js` are in `blah/__test__/foo.spec.js`.
To run all unit tests, execute the script `pnpm test`.
