FSDirectoryFactory (Maven-Indexer 6.1.1 API)

```
public interface FSDirectoryFactory
```
FSDirectoryFactory allows host application choose specific FSDirectory implementation used during index update. This is useful in some environments where default Lucene heuristics results in suboptimal choice of FSDirectory. For example, MMapDirectory used by default on 64 bit Linux JDK results in heavy operating system swap with certain Linux configuration and host application can choose NIOFSDirectory to avoid the problem.
