/// Return an the paths for all resources in |directoryPath| that have the
/// |extension| file extension.
///
/// Args:
///   extension - the file extension (excluding the leading ".") to match.
///               If nil, all files are matched.
///   directoryPath - the directory to look in.  NOTE: Subdirectories are NOT
///                   traversed.
///
/// Returns:
///   An NSArray of absolute file paths that have |extension|.  nil is returned
///   if |directoryPath| doesn't exist or can't be opened, and returns an empty
///   array if |directoryPath| is empty.  ".", "..", and resource forks are never returned.
