The application aims to show how to connect to a Socks4 proxy using async operations with ASIO. The SOCKS protocol is
briefly described by the diagram below.

# Configure and Building example
This example requires the proxy address to be configured. You can do this using the menuconfig option.
Proxy address and port must be configured in order for this example to work.
