-Examples:
-"**\*.class" matches all .class files/dirs in a directory tree.
-
-"test\a??.java" matches all files/dirs which start with an 'a', then two
-more characters and then ".java", in a directory called test.
-
-"**" matches everything in a directory tree.
-
-"**\test\**\XYZ*" matches all files/dirs that start with "XYZ" and where
-there is a parent directory called test (e.g. "abc\test\def\ghi\XYZ123").
-
-Example of usage:
-
-DirectoryScanner scanner = DirectoryScanner();
-scanner.Includes.Add("**\\*.class");
-scanner.Exlucdes.Add("modules\\*\\**");
-scanner.BaseDirectory = "test";
-scanner.Scan();
-foreach (string filename in GetIncludedFiles()) {
- Console.WriteLine(filename);
