/**
 * Used to send messages to the webview from the native parts of the app
 *
 * This was previously done with evaluateJavaScript on @"window.TheFakeWebSocket.onmessage([...someData...])" but that was very slow
 *
 * This code connects to MobileSocket (a class based on ProxySocket which is used to workaround restrictive firewalls that do not
 * allow websocket use). MobileSocket is also used on Android by the similarly-named MobileSocket Java class
 *
 * Return messages are still sent via calling native methods from JS rather than by sending through the MobileSocket. That's because in
 * Android it is not possible to read the body of an intercepted request, which prevents you from implementing the other side of the
 * ProxySocket protocol. Though there is no such technical restriction on iOS, it was deemed to be more helpful to keep the sending
 * mechanisms the same between the mobile apps. Similarly, long-running HTTP requests which continually receive partial data were ruled
 * out for similar reasons.
