Tyler Veness 3cd1253977 artf2612: Update license in source files.
Years update, references to WIND_BASE were removed, and WPILib license was
moved to the root directory of the project.

If there was already a comment block, a year range through 2016 was created
using the first year in the comment. If there was no comment block, a block
with just the year 2016 was added.

Comments were not added to files from external sources (NI, CTRE).

/**
* Use a rate gyro to return the robots heading relative to a starting position.
* The Gyro class tracks the robots heading based on the starting position. As
* the robot rotates the new heading is computed by integrating the rate of
* rotation returned by the sensor. When the class is instantiated, it does a
* short calibration routine where it samples the gyro while at rest to
* determine the default offset. This is subtracted from each sample to
* determine the heading.
*
* This class is for the digital ADXRS450 gyro sensor that connects via SPI.
