Glen Whitney a1fa83a007 test: Set up a mocha test harness
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`.

  Resolves #3.
