 * Project: Manually Configuring Particle WiFi Credentials From Application Code
 *
 * Description: Particle WiFi credentials can be set from the application code using the "WiFi.setCredentials()" function.
 *  There are, however, some caveats to actually making this work, as detailed by: https://patrick.ble.si/particle-manual-wifi-creds
 *  Additionally, that solution clears and re-stores all credentials every time the device starts up, theoretically 
 *  contributing to unnecessary flash wear on the WiFi module.  Additionally, if there are cached WiFi credentials actively 
 *  in use that are not present in the application code, the device will not be able to re-connect to WiFi after the new 
 *  application code is flashed.  So, this implementation first attempts to connect to WiFi using existing credentials, then 
 *  falls back to attempting to store and use the new ones.
