   @lewismc I can't get your NUTCH-2202 branch to build.
   
   I'm doing:
   ```
   git clone https://github.com/lewismc/nutch
   cd nutch
   git checkout NUTCH-2202
   ant
   ```
   
   which is giving me:

> We have recently released anthelion, which is a focused crawler plugin for structured
data which can be extracted with any23. (https://github.com/yahoo/anthelion) As proposed by
Lewis (Lewis John McGibbney) we think the integration of the parser (any23) and the scoring
function based on the online learner could be a good improvement for nutch.
