#3 tutorial example to fix

[Gianluca Moro]

Hi,

I'm testing Psilab for an application relating
respiratory gas analysis.
It seems really good.

Just a note relating the tutorial: in the plotting
example, you used ' ' instead of ", and the name
of the data are not x and y but xdat and ydat.

The correct line becomes:

plot2d ~x:[xdat] ~y:[ydat] ~title:"Testplot"
~xlabel:"X" ~ylabel:"Y" ~xrange:[0.0;20.0]
~yrange:[0.0;1.0]() ;;

This is really a minor note. You have done a
really good job!

Regards
Gianluca
