03/1/2017 - Had a meeting discussing problems in the patent data.
03/2/2017 - Created a new table proassigneend2. Cleaned some of the 'name' and 'city' records in ptoassigneend2. Created ptoassigneend_country table to store country information. Figured out some methods to fill the empty 'city'/'country' information. Created ptoassigneend_country table to store country information.
