+/* This driver uses the Adafruit unified sensor library (Adafruit_Sensor),
+   which provides a common 'type' for sensor data and some helper functions.
+   
+   To use this driver you will also need to download the Adafruit_Sensor
+   library and include it in your libraries folder.
+
+   You should also assign a unique ID to this sensor for use with
+   the Adafruit Sensor API so that you can identify this particular
+   sensor in any data logs, etc.  To assign a unique ID, simply
+   provide an appropriate value in the constructor below (12345
+   is used by default in this example).
+   
+   Connections
+   ===========
+   Connect SCL to analog 5
+   Connect SDA to analog 4
+   Connect VDD to 3.3V DC
+   Connect GROUND to common ground
+    
+   History
+   =======
+   2013/JUN/17  - Updated altitude calculations (KTOWN)
+   2013/FEB/13  - First version (KTOWN)
