finished more stuff.  struck that thit
Merge branch 'master' of https://github.com/LACodeAcademy/Zach
I redid the dividing tool, twice, just for some practice.  I think I made it better.  If you look at 'adding' and at 'redo' you will see changes I made in 'redo' in order to clean up the application.  Also used the class "FinishedTask" to strike out "The Adding Tool" under 'todo'.  Tomorrow evening I embark on the SQL todo.
