When are students free:
y1/s1	W: M9-2, M4-5,        T3-5,        R12-3,        F2-5
	X+AI:                 T3-5,               R4-5,  F2-5
	Y: M9-11, M4-5,       T3-5, W9-11,        R3-5,  F2-5
	Z: M9-2, M4-5,        T3-5, W9-11,               F2-5

	M: M9-11, M4-5, T9-2, T4-5,        W12-1, R3-5,  F2-5
	B: M9-11,                   W9-11,               F2-5

	I would like to use 1 slot for B+M CS102.
	I would like to have 1st & 2nd year tutorials at different times.

y1/s2:	W:                                          F3-5
	X: M9-2,                                    F3-5
	Y: M11-2,                                   F12-5
	Z:                                          F12-5

	M:               W9-10, W12-1, R10-3, R4-5, F2-5
	B:        T12-3,                            F3-5

	W are obviously a problem - they will just have to have a split
	wka/wkb CS107 slot (as it is rarely used) - either Monday morning,
	(+ if the 3rd CS122 lab is needed, Friday pm wkb).

	I would like to pick times for MT16x that are similar to last year,
	but unfortunately that is impossible - I have to talk to RonL!
