The new zoom implemented for ContinuousFunction is now factorized inside Function to benefit the Sequence class. The same things is done to code added to Graph::GraphController, which is moved into FunctionGraphController. This removes the reimplementation of several methods, most notably computeYRange, as the implementation for function is general enough to work on sequences.
