[Cs3] I updated the slides

[Mikhail Nesterenko]

- to describe STL extensions of the algorithms,
- to mention that template recursion (used in metapogramming examples)
  uses non-type parameters

Also note that the branching example in metaprogramming is a
re-implementation of is_same feature introduced in C++ that
we studied earlier. Shown in this example:
