Merge, update, and massage files to get data-test working again.
Trying to get JsonBox to work...
worked on Dept enums and parseID()
Remove GUI-related stuff
Move stuff to /unused
Remove moar GUI stuff
Restart work on data-test
On second thought, just get rid of the unused classes.
Switch data-department to tabs
Add "using namespace std;" to remaining header files
Switch to if/else statements for parseID
Update makefile
Remove data.hpp
Add department back as it's own thing.
Put dept_t back in data-general
Add the "source" Excel files to /data
Rename g to infile
Update Student to be the root of all classes
Make Department a class (again)

... but this time with *methods*!
Update updateID()
