/** A class for interfacing XSens 3rd generation Inertial Measuring Units
  *(IMUs), the "XSens MTi" model.
  *  It uses a serial port or USB-to-serial adapter to communicate to the
  *device, so no special drivers are needed.
  *  For the more recent 4th generation devices, see the class
  *mrpt::hwdrivers::CIMUXSens_MT4
  *
  *  See also the application "rawlog-grabber" for a ready-to-use application to
  *gather data from the scanner.
  *
  *  \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
  *        COM_port_LIN = /dev/ttyUSB0       ; COM PORT in LINUX (optional. If not
  *provided, the system will search the connected port)
  *        COM_port_WIN = COM1               ; COM PORT in Windows (optional. If not
  *provided, the system will search the connected port)
  *        baudRate                              ; Baudrate for communicating with the
  *COM port (mandatory for Linux)
  *                                                                 (for Windows, if COM_port_WIN is not
  *provided,
  *this
  *value is ignored)
