following question 

    1. Does every form created by "Shift-Ctrl-N" introduce a new 
    class? or just few functions are introduced?

is unswered already with help of "doodle" example 
provided in tutorial. After few years it is worth of 
revisiting it again :)

I hope Q2 will be answered soon as well...


kind regards,
Valery A.Khamenya
