# DirectoryTokenizer The DirectoryTokenizer is a class that can be used to recursively scan directories in a file-by-file manner rather than parsing the entire tree at once. ## Interface
    DirectoryTokenizer(std::string rootDirectory,
    		   unsigned maxDepth = 255u)
| Creates a DirectoryTokenizer object set to scan the specified rootDirectory, going at most maxDepth deep into the tree.
    bool next(std::string &fileName)
| Stores the name of the next file in fileName if there is one available. Return true if a file was found and fileName is updated; returns false if no next file is available. Once a false is returned, there are no files left in the directory tree and the scan is complete.
    bool ok() const
| Returns true if the object is in good state. Returns false if, for example, the rootDirectory could not be opened.
    bool complete() const
| Returns true if the scan has completed.
## Example Printing all files in the directory tree under the current directory:
    	cvmlcpp::DirectoryTokenizer dt(".");
    	std::string fileName;

    	if (dt.ok())
    	{
    		while(dt.next(fileName))
    			std::cout << fileName << std::endl;
    	}
    	else
    		std::cout << "ERROR!" << std::endl;
