Derive config from nested directory structure

[mjackson]

Remember when you used to just dump a bunch of PHP files into a directory and Apache would automatically know what to do?

It would be cool to have a directory structure like:

- apps
  - one
    - index.html
  - two
    - index.html
    - three
      -index.html

and then to be able to say history-server apps and it would automatically derive the following config:

[
  { path: '/one', root: '/apps/one' },
  { path: '/two/three', root: '/apps/two/three' },
  { path: '/two', root: '/apps/two' }
]

Then you could just dump a whole bunch of apps in the directory structure you like and not worry about having to recreate the config every time you add a new one.
