It hasn't.  Sadly the 2012 project just tailed off.  I'm not sure what
the current state is compared to the code on trunk - Parth probably has
more of an idea.

Cheers,

As Olly has already pointed out the 2012 branch is not merged.

I think there are some compilation errors in the branch.

The code in branch is better refactored. The Ranker and FeatureManager
classes are well defined and implemented.

Parth.
