Incompatible with YarnSpinner 2.x syntax

[Pennycook]

YarnSpinner 2.0 made some changes to the syntax. For example, [[Node]] is now written <<jump Node>>.

GDYarn currently ignores such jumps (presumably because they look like custom commands).

Yes, currently GDYarn is till 1.0 spec. I might do a gradual upgrade but maintain backward compatibility. I cannot give a time estimate of when this will be done.

If you would like to make a contribution let me know. I still need to go back and add unit testing in order to ensure no functionality is lost so it might be challenging to move forward until then.
