Update md file and add package-lock.json (#27)

In the last pr, the master build failed because
eslint-config-frontier-react updated after the pr was made, but before
it was merged, and that update included a change to the test.

Add package-lock.json to see changes better and not have a pr's checks
be possibly different than the master's checks due to deps changing
things between a pr creation and merge.

@fs/eslint-config-frontier-react@11.4.2 turned off
you-dont-need-lodash-underscore/clone-deep and that made the test fail
on master.
