USAGE: result=EyelinkDoTrackerSetup(el [, sendkey])

el: Eyelink default values

sendkey: set to go directly into a particular mode
sendkey is optional and ignored if el.callback is defined for
callback based tracker setup.

      'v', start validation  
      'c', start calibration  
      'd', start driftcorrection  
      13, or el.ENTER\_KEY, show 'eye' setup image  

Note that EyelinkDoTrackerSetup() internally uses Beeper() and Snd() to play
auditory feedback tones if el.targetbeep=1 or el.feedbackbeep=1 and the
el.callback function is set to the default PsychEyelinkDispatchCallback().
If you want to use PsychPortAudio in a script that also calls EyelinkDoTrackerSetup,
then read “help Snd” for instructions on how to provide proper interoperation
between PsychPortAudio and the feedback sounds created by Eyelink.
