Proper Socket.IO Latency Checking
/*
- Insert this after including / referencing socket.io.min.js.
- Point being:
- Client sockets *naturally* adapts its Ping Interval & Ping Timeout
from its server's settings, hence you can't actually those options here.
- We instead add an eventhandler for the "pong", and the actual millisecond latency,
and optionally to the "ping" too, in case you wanna see it in action.
