Detailed Description

A stream that supports seeking.

IMPORTANT: If you want to subclass this, override _seekToOffset:, _seekForwardWithOffset: and _seekToOffsetRelativeToEnd:, but nothing else. Those are not defined in the headers, but do the actual work. OFSeekableStream uses those and makes them work together with the caching of OFStream. If you override these methods without the _ prefix, you *WILL* break caching, get broken results and seek to the wrong position!
