Creates an FSDirectory instance, trying to pick the best implementation given the current environment. The directory returned uses the {@link NativeFSLockFactory}.

Currently this returns {@link SimpleFSDirectory} as NIOFSDirectory is currently not supported.

NOTE: this method may suddenly change which implementation is returned from release to release, in the event that higher performance defaults become possible; if the precise implementation is important to your application, please instantiate it directly, instead. On 64 bit systems, it may also good to return {@link MMapDirectory}, but this is disabled because of officially missing unmap support in Java. For optimal performance you should consider using this implementation on 64 bit JVMs.

Just like {@link #Open(File)}, but allows you to also specify a custom {@link LockFactory}.
