The CommandLineTokens class provides access to each token on the command line,
with semantics somewhat different from argc/argv.

With argc/argv, I found the following undocumented behavior:

1. A quoted string is mapped into an unquoted string.  For example,
           "12345" --> 12345

2. Backspace is the escape character for inputting a literal quote.  Examples: 
           123\"45 --> 123"45
           "123\"45" --> 123"45

3. Backspace is also used for inputting backspace-quote, backspace-backspace-quote, 
   backspace-backspace-backspace-quote, etc.  Examples:
           123\\"45 --> 123\"45
           123\\\"45 --> 123\"45
           123\\\\"45 --> 123\\"45
           123\\\\\"45 --> 123\\"45
   In general, 2n or 2n+1 backspace characters followed by quote maps into 
   n backspace characters followed by quote.


The special interpretation of backspace-quote is unsatisfactory in KeePass 
for at least two reasons:

1. A master password command line argument can contain a quote or n
   backslash characters followed by quote.  There should be a reasonably 
   natural way to code them.

2. Some KeePass plugins (which reuse KeePass command processing code) have
   path command line arguments such as /backup.path:"C:\"   It would be
   very unfriendly if users had to enter this as /backup.path:"C:\\"


The CommandLineTokens class parses the raw command line from Win32 
GetCommandLine() into tokens using the following simple rules:

1. A quoted string is mapped into an unquoted string.  For example,
           "12345" --> 12345                  (SpaceBalls password)

2. Quote is the escape character for inputting a literal quote.  Examples: 
           123""45 --> 123"45
           "123""45" --> 123"45

Thus, the backslash has no special status, and can be used in a natural
way in passwords and paths.

If the input command line contains an unmatched quote, the 
displayIgnoredMessage() member function is invoked (displaying a
suitable MessageBox), and the final (incomplete) token is not appended 
to the container.  displayIgnoredMessage() is public for reuse by 
the CmdArgs class.

CommandLineTokens uses the singleton design pattern.
CommandLineTokens objects are immutable.

class CommandLineTokens {
public:
    typedef std::vector<std_string> string_vector;
    typedef string_vector::const_iterator const_iterator;

    const_iterator begin() const {return m_TokenContainer.begin();}
    const_iterator   end() const {return m_TokenContainer.end();}

    static const CommandLineTokens& instance();
    static void displayIgnoredMessage(const std_string& argument, const std_string& reason);

private:
    CommandLineTokens();

    string_vector m_TokenContainer;        
};
