This class represents a android.hardware.Sensor Sensor event and
holds information such as the sensor's type, the time-stamp, accuracy and of
course the sensor's SensorEvent#values data.

<u>Definition of the coordinate system used by the SensorEvent API.</u>
The coordinate-system is defined relative to the screen of the phone in its default orientation. The axes are not swapped when the device's screen orientation changes.
The X axis is horizontal and points to the right, the Y axis is vertical and points up and the Z axis points towards the outside of the front face of the screen. In this system, coordinates behind the screen have negative Z values.

<b>Note:</b> This coordinate system is different from the one used in the Android 2D APIs where the origin is in the top-left corner.
