Small wrapper around a fp object which will tee everything read into a
buffer, and when that file is closed it will execute a callback with the
contents of that buffer.
All attributes are proxied to the underlying file object.
This class uses members with a double underscore (__) leading prefix so as
not to accidentally shadow an attribute.
