I would like to thank everyone who helped me writing thesis. This includes but
is not limited to Rinus and Pieter for the support, supervision and weekly
sparring. Bas for providing the needed \gls{iTasks} support. Arjan for the
sparring and coffee. George, Camil and others\todo{proofreaders}\ for
proofreading and  Camil for lifting \emph{Cloogle} to a solid search engine I
used daily. Finally I would like to thank my family, friends and wife for
listening to a year of endless rambling on this.
