In notebooks 4-8, the exercises have been moved to the sections in the tutorial explaining the topics needed to do the exercises. A number of new exercises have also been added. I also made a minor textual revision in notebook 11 (the instruction in exercise 11.1. to give the dataframe a name that is distinct from that of the dataframe used in the tutorial)
