Recurse Source File Directories

[JakeWharton]

I would very much like to see GuiceyDataGenerator recurse into subdirectories when parsing directories.

Here is an updated parseDirectory method:

private void parseDirectory(File directory, TypeParser parser) {
    for (File file : directory.listFiles()) {
        if (file.isFile()) {
            for (String extension : _fileExtensions) {
                if (file.getName().endsWith(extension)) {
                    parseFile(file, parser);
                    break;
                }
            }
        } else if (file.isDirectory()) {
            parseDirectory(file, parser);
        }
    }
}

I just noticed that you have this block in parseFile of the same file:

if (file.isDirectory()) {
    parseDirectory(file, typeParser);

This will (likely) never get hit as-is because of the extension checking in the current parseDirectory method. The only way it would happen is if one of the subdirectories names ended in one of the extensions.

If you implement the method above, you can remove these two lines from parseFile.

I'll be doing this on a fork (among other upgrades) and sending pull requests soon.
