+// I2Cdev library collection - MPU6050 I2C device class
+// Based on InvenSense MPU-6050 register map document rev. 2.0, 5/19/2011 (RM-MPU-6000A-00)
+// 10/3/2011 by Jeff Rowberg <jeff@rowberg.net>
+// Updates should (hopefully) always be available at https://github.com/jrowberg/i2cdevlib
+//
+// Changelog:
+//     ... - ongoing debug release
+
+// NOTE: THIS IS ONLY A PARIAL RELEASE. THIS DEVICE CLASS IS CURRENTLY UNDERGOING ACTIVE
+// DEVELOPMENT AND IS STILL MISSING SOME IMPORTANT FEATURES. PLEASE KEEP THIS IN MIND IF
+// YOU DECIDE TO USE THIS PARTICULAR CODE FOR ANYTHING.
