MatFileReader/MatFileReader do not implement java.lang.AutoCloseable

[lukehutch]

The following does not work on Java 8:

    try (MatFileReader reader = new MatFileReader("test.mat")) {
        // do something with reader without the need to explicitly close() it
    } catch (IOException e) {
        e.printStackTrace();
    }

For this syntax to work, MatFileReader and MatFileWriter should implement the java.lang.AutoCloseable interface.

Ah, never mind, I guess MatFileReaders and MatFileWriters don't need to be manually closed anyway?
