Highlight values that are diferrent between potential pairs - manual dedup

[TNRiley]

highlighting the values that are different between record1 and record2 could help users more quickly analyze the flagged pairs. Maybe yellow for values where one is missing and red for values that are not exactly the same (we could make this a calculation based on how different too, but for simplicity exact match would be a step forward).

Agree this would be useful. I tried exploring adding different colours but thought it maybe looked a little too multicoloured/distracting.

In branch https://github.com/ESHackathon/CiteSource/tree/aesthetics - I have added a styling feature with colours and bolds exact matches (>99.9%) for quicker manual dedup.
