Closes this file system.
After a file system is closed then all subsequent access to the file
system, either by methods defined by this class or on objects associated
with this file system, throw ClosedFileSystemException. If the
file system is already closed then invoking this method has no effect.
Closing a file system will close all open channels, directory-streams,
watch-service, and other closeable objects associated
with this file system. The default file
system cannot be closed.
