Flatten the directory structure

[kennylavender]

Lots of nested folders and tests in different locations currently.

Something like this should be easier to update and manage.

Suggestions welcome.

This will be a breaking change to any project directly importing files

dist
source
  integration/
    |-- react-context.js
    |-- express.js
    |-- index.js
  test-fixtures/
    |-- createFeature.js
    |-- createFeatures.js
  test/
    |-- configure-features.js
    |-- create-route-middleware.js
    |-- get-enabled.js
    |-- get-is-enabled.js
    |-- is-feature-included.js
    |-- with-features.js
    |-- index.js
  |-- configure-features.js
  |-- create-route-middleware.js
  |-- get-enabled.js
  |-- get-is-enabled.js
  |-- is-feature-included.js
  |-- with-features.js
  |-- index.js
