Refactored mixins into utils
ES2015 module exports
ES2015-style imports
WIP Fixing tests
Fixes tests after es2015 code migrations.
We we're require()ing an ES2015 module[1]. Have to make sure you account
for the .default in this case.
[1] We had to use ES5 `require` in Jest:
(https://github.com/babel/babel-jest/issues/16)
- Make backend address configurable via env variable
- `BACKEND_HOST=1.2.3.4:4040 npm start` points the frontend to the app on that server. Just for development
- Render control icons
- removed close x for details panel
- added control icons in its space
- closing of panel still works by clicking on same node, or background
- Dont allow control while pending
- Render and auto-dismiss control error
- Make tests pass
