Bootstrapping secondary code words

[JherezTaylor]

For words that pass requirement 1 of #116 but not requirement 2 we do the following:

1. Check if these words share some correlation with the cw list obtained in #116 (relatedness and similarity)
2. If there are matches above a support threshold then we flag these words as secondary cw
3. The idea here is to keep bootstrapping and expanding the list of cw

• [] Keep track of words that pass req 1 only
• [] Define function to check for correlation with the words in cw
• [] Define support threshold

We may find that the expanded HS list contains patterns that mix with functional words to create a HS inference.
