The script was written as an example for my students. Glad it was useful 
to you.

With all the elements in place, especially with Pietro's recent work, it 
should be quite easy to create a unifying module 'i.segment.classify' 
which would take as input

- the segments coming out of i.segment
- training zones
- a choice of variables
- a choice of classifier

would then calculate the chosen variables, submit the results to the 
classifier and then update the segment map attribute table with the 
classification result. In other words a frontend combining v.to.db, 
v.rast.stats, v.class.ml and possibly some others.
