用C++实现六自由度的机械手的运动学正反解问题，并用MFC做界面实现-resolve the inverse kinematics problem of the robot,and use the MFC interface to realise the input and output

四自由度机器人正逆运动学解算，亲测有效，实现单点解算及检测，较具有参考价值-Four- freedom robot inverse kinematics solver positive, pro-test effective, single-point solver and testing, compared with a reference value
