Highscore and statistics

After every run (max. 5 minutes) a highscore is shown with the following equation:

duration_with_penalty = duration_in_seconds + not_completed*ERROR_PENALTY
score = 100000/duration_with_penalty - 124

not_completed is the number of not-yet-solved problems (empty fields, max 100). ERROR_PENALTY is a time penalty (5 seconds). Hence, the max value for duration_with_penalty is 800 = (300 + 5*100) and 100000/800 = 125 -> score = 1

Für every test run the name, date/time, duration and number of unsolved problems (free tiles) is stored. The information is stored in a csv-file (tab-separated), which is writen into the user's home directory:

• Windows: %HOME%/AppData/Roaming/Rechenmeister/statistics.csv
• Unix/Linux: ~/.local/share/Rechenmeister/statistics.csv
