IF YOU ARE HAVING TROUBLE RESIZING THE SCREEN 
YOU MIGHT  TRY THESE COMMANDS:
sudo apt-get update
sudo apt-get install virtualbox-guest-additions-iso
sudo apt-get install virtualbox-guest-dkms 
sudo dpkg-reconfigure virtualbox-guest-dkms


THESE ARE USEFUL TO DEFINE

NOTE: these are unedited notes as to how I setup the xFitter environment. 
These are not complete, but they may be useful if you want to 
set up the tutorials on your machine at home.
