无限传感器多边测距，用4边方式定防区机器人的位置，相比卡尔曼算法，是比较粗糙的定位算法-Sensors Unlimited multilateral ranging, set of 4 side of the way the location of the robot defense area, compared to the Kalman algorithm, which is a more rough positioning algorithm

基于面向对象的c++程序，含有界面，略微粗糙，初次尝试，还请见谅-Based the object oriented c++ program, contain interface slightly rough first attempt, but please forgive me
