 * WiFi Credential Manager example
 * Written by Clyne Sullivan.
 * 
 * This Arduino sketch stores WiFi SSID and passkey information in non-volatile
 * EEPROM in order to connect to a given network. If these credentials are not
 * saved, an access point will be started with a web server allowing the user
 * to input new credentials. The access point can also be started by grounding
 * the "CredsResetPin" pin (default pin 0).
