/*
Variables Explained:
Floats: X,Y and Z refer to the position of the player who types the command
Floats: X2, Y2 and Z2 refer to the position of the player currently being compared
CountStage determines where the counter is at, 0 means it is off
timer stores the timerid used in the KillTImer()
Float dist stores the distance found in the Distance stock
pname[] is the Playername, string[] is the string sent, frozen[] stores the players freeze status (on(1) or off(0))
Freeze determines whether player freezing is on/off - it is changed ingame with the command /togfreeze
