How to use module MTI in few points :

  - don't read MTI.pdf, it is obsolete
  - the first thing you need to do is to call init. In argument, you need to
    pass the MTI serial port. On Dala, it is /dev/ttyUSB0.

		MTI::Init "/dev/ttyUSB0"

  - Your MTI is running :D

  - You can log the output of MTI with MTI::Log "filename", and stop the log
    with MTI::Stoplog 

  - If you want to couple it with rflex (what you really want to do in fact),
    you need :
		- init the MTI
		- do your stuff with rflex
		- call Rflex::SetOdometryMethod	RFLEX_ODO_3D 0 "MTISePos"

	if you don't init MTI before calling SetOdometryMethod, it will fail and
back to ODO_2D.
