In todays's 4th hour class, when we did the indction proof 
there was (legitimate) confusion between the state named A 
in the example and the set of accepting states whose generic 
name is A.

To alleviate this, I went back through the slides and changed 
the names of the states form A, B, and C to q0, q1, and q2.
If I missed making any of the changes that I should have made,
so that A,  B, or C still appears, please let e know so I can
change it.
