Using your work in this lab as a guide, create a three$-$level directory structure for your family tree $($grandparents$,$ parents, children$).$ You will need to create user accounts for each member of the family $($at least $2$ in each generation$),$ create groups for each generation, and then secure the folders so that only members of a single generation can write to files within that generation$$s directory. You may use fake names if you prefer.
