/**
 * @example web_setup/example.cpp
 *
 * This is an example of using the web setup network API to
 * configure the module network credentials remotely.
 *
 * It works as follows:
 * 1. Instantiate the WiConnect Library
 * 2. Initiate Communication with WiFi Module
 * 3. Start WebSetup with specified parameters
 * 4. Wait for web setup webpage to complete
 * 5. That's it!
