  Module Operations: 
  ==================
  This module defines a Form that displays grammatical constructs
  from a selected C++ source file.  It uses the services of four other
  modules:
  - Parser is responsible for identifying and reporting specific
    grammatical constructs.  It does this by collecting a sequence of
    tokens, called a semi-expression, from a source file, and analyzing
    that with a set of rules.  Any rule that succeeds generates some
    kind of output by means of one or more associated actions.
  - ActionsAndRules is provided to support addition of parsing actions,
    and rules not provided by the reusable Parser module.
  - SemiExpression is responsible for collecting a set of tokens for
    Parser to analyze.  It is SemiExpression's job to return just the
    right amount of information for each parsing analysis.
  - Tokenizer provides a stream of tokens (words) extracted from a
    source code file by throwing away all whitespace except for new
    lines, and separating indentifier characters from punctuation.

  Public Interface:
  =================
  This Executive module provides services, not through a software
  interface, but through a set of controls provided on a form,
  provided to allow a user to control the files analyzed and see
  the results of that analysis.

  Build Process:
  ==============
  Required files
    - Executive.cpp, Parser.h, Parser.cpp, DerivedActions.h,
      SemiExpression.h, SemiExpression.cpp, tokenizer.h, tokenizer.cpp
  Build commands (either one)
    - devenv Project1HelpS06.sln

  Maintenance History:
  ====================
  ver 1.0 : 12 Jan 06
  - first release
