/** A class for interfacing XSens 4th generation Inertial Measuring Units
 * (IMUs): MTi 10-series, MTi 100-series.
 *  Usage considerations:
 *    - In Windows, you only need to install XSens drivers.
 *    - In Linux, this class requires the system libraries: libusb-1.0 &
 * libudev (dev packages). Accessing USB devices may require
 *      running the program as super user ("sudo"). To avoid that, Or, install
 * <code> MRPT/scripts/52-xsens.rules </code> in <code>/etc/udev/rules.d/</code>
 * to allow access to all users.
 *
 *  For the older 3rd generation devices, see the class
 * mrpt::hwdrivers::CIMUXSens
 *
 *  \code
 *  PARAMETERS IN THE ".INI"-LIKE CONFIGURATION STRINGS:
 * -------------------------------------------------------
 *   [supplied_section_name]
 *    pose_x=0      // Sensor 3D position relative to the robot (meters)
 *    pose_y=0
 *    pose_z=0
 *    pose_yaw=0    // Angles in degrees
 *    pose_pitch=0
 *    pose_roll=0
 *    sensorLabel = <label>   // Label of the sensor
 *    ;sampleFreq  = 100  // The requested rate of sensor packets (default:
 * 100Hz)
 *    ; If a portname is not provided, the first found device will be opened:
 *    ;portname_LIN = USB002:005
 *    ;portname_WIN = \\?\usb#vid_2639&pid_0003#...
 *    ;baudRate     = 115200             ; Baudrate for communicating, only
 * if the port is a COM port
 *  \endcode
 *
 *  \note Set the environment variable "MRPT_HWDRIVERS_VERBOSE" to "1" to
 * enable diagnostic information while using this class.
