cli needs to be able to read N directories

[peterbe]

At the moment, the main argument to the cli is a list of files. E.g.

yarn run run ../stumptown/packaged/html/reference/elements/*.json

which is expanded by bash so it basically corresponds to typing

yarn run run ../stumptown/packaged/html/reference/elements/abbr.json
yarn run run ../stumptown/packaged/html/reference/elements/address.json
...

What would be ideal is to be able to pass a list of files or directories and if it's a directory I think it should drill down recursively by default. E.g.

yarn run run ../stumptown/packaged/html/reference ../stumptown/packaged/css/ some/other/directory some/other/specific/file.json

I blogged about the function that made this possible: https://www.peterbe.com/plog/function-expandfiles
