+/*************************************************************************
+ * Dragonfly Example program for 2015 AT&T Government Solutions Hackathon
+ * 
+ * The following hardware is required to successfully run this program:
+ *   - MultiTech UDK2 (4" square white PCB with Arduino headers, antenna
+ *     connector, micro USB ports, and 40-pin connector for Dragonfly)
+ *   - MultiTech Dragonfly (1"x2" green PCB with Telit radio)
+ *   - Seeed Studio Base Shield
+ *   - Grove moisture sensor (to connect to Base Shield)
+ *   - Grove button (to connect to Base Shield)
+ *   - MEMs Inertial and Environmental Nucleo Expansion board (LSM6DS0
+ *     3-axis accelerometer + 3-axis gyroscope, LIS3MDL 3-axis
+ *     magnetometer, HTS221 humidity and temperature sensor and LPS25HB
+ *     pressure sensor)
+ *
+ * What this program does:
+ *   - reads data from all sensors on MEMs board and moisture sensor on a
+ *     periodic basis
+ *   - prints all sensor data to debug port on a periodic basis
+ *   - optionally send a SMS containing sensor data when the Grove Button
+ *     is pushed (phone number must be configured)
+ *   - optionally send sensor data to AT&T M2X cloud platform (user must
+ *     create own M2X account and configure a device) if sensor data
+ *     crosses established thresholds
+ *
+ * Setup:
+ *   - Correctly insert SIM card into Dragonfly
+ *   - Seat the Dragonfly on the UDK2 board
+ *   - Connect an antenna to the connector on the Dragonfly labled "M"
+ *   - Stack the Base Shield on the UDK2 Arduino headers
+ *   - Connect the Grove button to the D8 socket on the Base Shield
+ *   - Connect the Grove moisture sensor to the A0 socket on the Base
+ *     Shield
+ *   - Stack the MEMs board on top of the Base Shield
+ *   - Plug in the power cable
+ *   - Plug a micro USB cable into the port below and slightly to the
+ *     left of the Dragonfly (NOT the port on the Dragonfly)
+ *
+ * Go have fun and make something cool!
