- cartesianProduct is not needed : getCellKeyList can do the same thing in a better and cleaner way
- if movements already exists, we don't want to take only the first one, but all movements are needed
- improve error message to display the Line (title and relative_url) and the coordinates of the not found cell. This will make debugging much more easier
- to set quantity on new created movements, we search on movement_list if movements contribute to the current movement applied on, but we need to look also on already processed movements (current_aggregated_amount_list)
- the condition to check if the quantity of the current movement should be updated was wrong, fix it
- in TradeCondition, now one loop turn is enought to make all calculation
- change some variables names that where already used previously to avoid mistakes
