Return results to a Results() object instead of a list of dicts

[ReedJessen]

results are currently returned to a list of dicts. Perhaps results should be returned to a Results() object which has some helper methods in addition to the list of dicts.

For example, Results().assets would be a list of dicts but Results().inventors would be a deduplicated list of all inventors found in in the query results. Similarly, Results().owners would be a list of owners.
