Column description for the static.adam4eve.eu CSV export

---- MarketOrderTrades ----
Adam4Eve compares market orderbooks every 15 minutes and checks if the volume in orders has changed or orders have disappeared. 
From this A4E deducts the trade transactions that have taken place on the market.
Since this is very resource intensive, this is only performed for the top trade hubs.
