Map Rank Feature: Date/Timeframe Map Rank

Concise description:
Specifics:
This will improve the following aspects of the site:
- Having a Map Rank Feature that allows one to see how poorly/well one has done over the last week/month/year/etc...
Specifics:
- Since I personally have been on since 2006, I would like to know how I have done in my first year premium year compared to my second year. I am now in my third premium year, so having something like this would be good to see if I have learned something or not.
This would also be good for the new Hall of Fame that is coming soon. It would allow jury members to look over a period of time to check consistency and other criteria we are currently working on.
This will improve the following aspects of the site:
- well of course if one was interested in using it, they could see if they've improved on certain maps, what maps they've played recently, without determining what dates are associated with game numbers. Otherwise, it is going to be a long drawn out process to look it up.
