* Proper handling of keyword arguments was implemented in Operators and ContextFunctions, as well as in methods of Interface0D, Interface1D, Iterator, their subclasses, Noise and IntegrationType. * Operators' methods and functions in the ContextFunctions module were renamed from CamelCase to lower cases + underscores. Style modules were updated accordingly. * Additional code clean-up was also made.
