Text::CSV::Track::Max - same as Text::CSV::Track but stores the greatest value
This documentation refers to version 0.3.
see Text::CSV::Track as this is inherited object from it.
Only difference to Track is that before value is changed it is compared to the old one. It it's higher then the value is updated if not old value persists.
Overridden function from Text::CSV::Tack that stores value only if it is greater then the one before.
