Wordnet similarity: HSO algorithm

Search by 'word#n#1'

HSO implementation - slow...

Don't do stemming if searching with position and sense

Synonyms wrapped with a lazy-seq

Add path to HSO, and reduce pointers in grouped-synset traversers

Aggregated tests

Don't automatically include synonyms in the fetch map - causes backbreaking performance issues

* Include the path in the HSO result
* Performance improvements

Reflection warnings & re-org imports

Fix test

Remove unnecessary files
