Dear Andreas and Fabian
wow that's pretty wonderful - thank you for all the great comments!
Dear Andreas, yes - you are absolutely right, when i tested it in my local linux machine
i had the second and third line (i.e the graphic outputs) commended out...
So,i tested only the first line, saw that it worked , got exited and started immediately try and create the git patch.
Meanwhile , i commended out the other two lines - thinking that i will test them too - but i finally never did
(i forgot cause i was too nervous and exited to send you guys the patch!).
I promise to be much more calm and precise in the future.
I am definitely going to keep on working on this, i 'll hit you up with more comments and questions soon.
Thank you all again!
Kate
