 /******************************************************
 This class.... is a mess ;-)
 It's does some kind of wrapping around libparted, but it's not very clear and it looks like shit.
 The one thing i have to say in favor of it is: IT JUST WORKS :)
 
 When i've time i will look into it and try to sort things out a bit. 
 Maybe building a small decent wrapper or so...
