twalpole/apparition: Capybara driver for Chrome using CDP

Apparition is a driver for Capybara. It allows you to run your Capybara tests in the Chrome browser via CDP (no selenium or chromedriver needed) in a headless or headed configuration. It started as a fork of Poltergeist and attempts to maintain as much compatibility with the Poltergeist API as possible. Implementing the capybara-webkit specific driver methods has also begun.
