[Cs3] function objects, mismatch algorithm

[Mikhail Nesterenko]

CS3 students,

I found out that the targets of the std:function discussed today
(slide 14) are uniformly referred to as _function objects_ I updated
the slide, let's stick to this terminology.

mismatch() returns a pair of iterators to the first mismatched element
in each matching range. I updated the example here:

   http://antares.cs.kent.edu/~mikhail/classes/cs3/Examples/STLAlgorithms/NonModifying/comparisonAlgorithms.cpp

and the slides to indicate that.

Thanks,
