Archana's AoA Point Decay Calculator

How To Use:
Get a program that can run a java file, and copy and paste the following text into that program.
Next, go to http://my.age-of-aincrad.com/function/full_leaderboard.php, and copy the data there, starting with the 1 at the very beginning (Don't include the text at the top, that's important. Example first line: 1	Konata	101222471	29920) and going to the very last person. Create a text file in the same folder as the program, titled leaderboard.txt (no caps, else there'll be an error) and paste all the info into it.
Lastly, run the program. It will tell you how fast your multiplier will decrease.
