  /* TIME ATTACK GAME SETTINGS PARAMETERS NOTE:
   * ------------------------------------------
   *  
   *  FORMAT :
   *  --------
   *    {"tm": 10, "le": false, "lm": 10}
   *
   *    tm : count down timer starting value
   *    le : stands for limit enable, if is TRUE the game end if target value is meet
   *    lm : targeted amount of kicks
   *  
   *  THINGS THAT ENDS THE GAME :
   *  ---------------------------
   *    1. BY COUNT DOWN "tm" REACH TO ZERO
   *    2. BY A COMMAND "FROM APP VIA BLUETOOTH"
   *    3. BY LIMITS MEET "WHEN NUMBER OF YOUR KICKS REACH TO lm VALUE"
   *  
   *  CALCULATING RESULTS :
   *  ---------------------
   *    Rapid Kick Speed = Number Of Kickes Made / Elasped Time In Sec
   *    Delay Between Kicks = Time Of Current Kick - Time Of Last Kick
   *  
   *  RETURNNING DATA FORMAT :
   *  ------------------------
   *    {"tm" : 82, "ct" : 10, "dl" : 1234, "st" : 585}
   *    
   *    tm  : timer count in Sec
   *    ct  : strike counter (number of kicks)
   *    dl  : delay between strikes
   *    st  : time stampe of the strike in milli Seconds
