[CSI] refactoring and debugging

[Mikhail Nesterenko]

CSIB students,

This is regarding the program refactoring (name changing) in visual
studio and compilation modes.

* Refactoring is modifying the program structure without altering its
  behavior. Often refactoring is done to "clean up" or improve the
  readability of the program. For example, change the name of a
  variable or class to better reflect its purpose. To rename a
  construct in visual studio, type ctrl+r, ctrl+r, or right-click on
  the name and select Rename from the drop-down menu. Unlike more
  simple search and replace option available in Edit --> Find and
  Replace --> Quick Replace (Ctrl-H), variable renaming is aware of
  the syntax and replaces the name only of this construct.

  I added this information to the features of MSVS here:
  http://www.cs.kent.edu/~mikhail/classes/csi/Labs/MSVS/features.html

* A compiled executable in release mode does not have references of
  either source-code variable names or line numbers. An executable
  compiled in debug mode retains these references. A compiled
  executable in release mode does not have references of either
  source-code variable names or line numbers. An executable compiled
  in debug mode retains these references.
