[CSI] Lab 7 opened

[Mikhail Nesterenko]

CSIA students,

I opened lab 7. This lab will be assigned in CSIB. So it is not part
of CSIA. You are not required to do or submit this lab for
CSIA. However, you can use the lab to practice strings and file I/O
which is studied in CSIA. The lab instructors would be happy to look
at your lab submissions and critique them if you like, but they will
not grade them until CSIB.

Thanks,
