* Add new test suite test/data-quality-tests.js
* Make ParseBook exported so I can use it to get data for each book
This is suboptimal since really the data should be in a look up table
somewhere but I don't want to tackle that in this change.
* Actually load the json data for each book and test that number
of chapters exists.
* Add package.json to tell npm what dependencies we need.
* Use npm's test package for the assertions
* Add a test/all.js as our test suite entrypoint.
* Port biblerefparsing tests over to the new unit test framework.
