close() method missing?

[ronburk]

I'm a little confused by the fact that closing is mentioned many times as a concept, it appears there is a close() method that I'm calling successfully under Chrome, and yet I don't see any actual explicit documentation of a close() method.

FileSystemWritableFileSteam (what you get when you call handle.createWritable()) extends WritableStream, which has a close() method.

SyncAccessHandle also has a close() method, though specifying this is still a WIP. See #21
