Subsections are alphabetized according to lexographic ordering. Also, HAL includes were moved from headers to source files where possible. This change may cause user code which uses HAL functionality and does not include the relevant HAL header (since it may have been provided by another WPILib header) to fail to compile.

/**

|
* 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.
