/**
 * Raspbian WiFi Configuration Portal
 *
 * Enables use of simple web interface rather than SSH to control wifi and hostapd on the Raspberry Pi.
 * Recommended distribution is Raspbian Buster Lite. Specific instructions to install the supported software are
 * in the README and original post by @SirLagz. For a quick run through, the packages required for the WebGUI are:
 * lighttpd (I have version 1.4.53 installed via apt)
 * php-cgi (I have version 7.1.20-1+b2  installed via apt)
 * along with their supporting packages, php7.1 will also need to be enabled.
