// Regular-expression based scanner for parsing an input stream.

//

// Example 1: parse a sequence of "var = number" entries from input:

//

//      Scanner scanner(input);

//      string var;

//      int number;

//      scanner.SetSkipExpression("\\s+"); // Skip any white space we encounter

//      while (scanner.Consume("(\\w+) = (\\d+)", &var, &number)) {

//        ...;

//      }
