Use lerna to publish packages to npm so to allow 2 usage scenarios:

• desktop flavor, which should run the electron app by simply running:
  • npm i -g autocannon-ui-desktop
  • autocannon-ui-desktop
• web flavor, which may require some changes in package names to make it a little more straightforward and which should allow running a standalone web version which exposes both the HTTP API and the UI and run as an executable bin:
  • npm i -g <sensible package name> (e.g. autocannon-ui-web)
  • <sensible package name>, which will start the server on a default port, print it to the console and tell you to navigate to http://localhost:
