+/* PLEASE READ THIS!
+ * The following fields must be populated in order to properly send data to the "Default ThingFabric Project" in your 2lemetry account using the MQTT client
+ * You must have a hacker (or higher) account at http://app.thingfabric.com
+ * After you register and login, follow the steps below to set up your client
+ * Click on "Default ThingFabric Project"
+ *      Set _2LEMETRY_DOMAIN to the string after "Project" at the top of the page
+ * Click on "Credentials"
+ * Click on "Default ThingFabric Credential"
+ *      Set _2LEMETRY_USER_ID to the value in the "Key (Username)" field
+ *      Set _2LEMETRY_TOKEN to the value in the "MD5 Secret" field
+ * If you are running this code on multiple devices, you will want to make the _2LEMETRY_DEVICE_ID field unique for each device
+ * Set the _APN field to the APN provided with your sim card
+ * Build, flash, and run
+ *      This code sends a random integer value approximately every 30 seconds
+ * Click on "Default ThingFabric Project"
+ * Click on "Analytics"
+ * You should be able to see your test data (page needs to be refreshed periodically, it doesn't automatically refresh)
