First iteration of successful rhyme assoc. extract

- Successfully extracting, in an ‘easy-to-explode’ format, the data
that references other rhyming indexes.
-  One query will be run for post-explosion comparison for each word.
Pair extraction and evaluation

- Extracted rhyme pairs for each word in the DB.
- Returned the same list as a sorted CSV string for ease of parse
later, although relative tables could be another use option.
- This will lead up to the prepend of the actual learned values AND
their associated rhyming words.  The DB will also by nature organize
and sort the indexes by itself.
