[cs13001] lab 7 hints

[Mikhail Nesterenko]

CSI students,

I updated the lab assignment with the following links:

- This code 
  http://vega.cs.kent.edu/~mikhail/classes/csi/Labs/Lab7/findAll.cpp
  demonstrates how multiple occurrences of the same character may be
  found using the version of find() which specifies the starting
  position of the search. Similar versions are available for all
  string search functions.

- This code
  http://vega.cs.kent.edu/~mikhail/classes/csi/Labs/Lab7/printfile.cpp
  demonstrates how to read a file line-by-line.

Thanks,
