[WIP] WebSocket server for Pathfinder

####Requirements:

1. A working instance of Pathfinder (>= v1.2.0).
2. A working installation of ØMQ (>= v4.2.0). Which is a "network library" written in C (very fast) that handles TCP based socket connections between your existing Pathfinder installation and this WebSocket server extension. download ØMQ.
3. A new PHP extension for ØMQ that handles the communication between this WebSocket server and ØMQ. (>= v1.1.3)

####Install: Make sure you meet the requirements before continue with the installation.

1. Install Composer
2. Install Composer dependencies from composer.json file:
   • $ composer install OR
   • $ php composer.phar install (change composer.phar path to your Composer directory)
3. Start WebSocket server php cmd.php

####Default Configuration Clients (WebBrowser) listen for connections

• Host:0.0.0.0. (=> any client can connect)
• Port:8020
• URI:127.0.0.1:8020 (Your WebServer (e.g. Nginx) should pass all WebSocket connections to this source)

TCP Socket connection (Internal use fore WebServer <=> WebSocket communication)

• Host:127.0.0.1 (=> Assumed WebServer and WebSocket Server running on the same machine)
• Port:5555
• URI: tcp://127.0.0.1:5555

[Optional] The default configuration should be fine for most installations. You can change/overwrite the default Host and Port configuration by adding additional CLI parameters when starting the WebSocket server:

php cmd.php --pf_listen_host [CLIENTS_HOST] --pf_listen_port [CLIENTS_PORT] --pf_host [TCP_HOST] --pf_port [TCP_PORT]
