Win/weapon correlation info

Correlation between main primary weapon used and victory in round.

Example correlation coefficient values

correlation coefficient 0.06 of Deagles_x1 over 100 rounds where it was tagged could mean that
- 53 were won by that team
- 47 were lost
correlation coefficient -0.04 of Deagles_x1 over 100 rounds:
- 48 were won by that team
- 52 were lost
correlation coefficient 0.00 of Deagles_x1 over 100 rounds:
- 50 were won by that team
- 50 were lost

each round's kill log is checked
if one player used a weapon for more than 50% of his primary-weapon-kills then tag for that team is created, eg SteyrAUG_x1
if there are two players in the team using mainly the same primary weapon in that round, that "team-round" will be tagged with SteyrAUG_x2 instead of two SteyrAUG_x1
win or lose tag is added for each "team-round"
entries are roughly like this for each round:
- "game 123123, round 0, team Red, tags: SteyrAug_x2, Deagles_x1, win"
- "game 123123, round 0, team Blue, tags: M79_x1, MP5_x1, lose"
rounds that ended with Tie are ignored altogether
data is filtered to only include balanced games from correct playlist (see "Parameters" section)
finally correlation is calculated between win tag and all other tags using Pearson correlation coefficient
