Class SimpleFSDirectory

A straightforward implementation of FSDirectory using System.IO.FileStream. However, this class has poor concurrent performance (multiple threads will bottleneck) as it synchronizes when multiple threads read from the same file. It's usually better to use NIOFSDirectory or MMapDirectory instead.
