说明：  实现求解平面最近点对的复杂度为nlgn的算法。程序要求能够自动生成至少100万个点，并利用该算法求解。此外，要求支持图形界面的算法输入与输出。在此基础上，添加n^2级算法的实现，并比较相同规模下，两种算法的时间消耗。
(Solving the nearest point on the plane to achieve the complexity of the algorithm for nlgn. Program requires the ability to automatically generate at least 1 million points, and the use of the algorithm. In addition, the algorithms required to support graphical user interface input and output. On this basis, add the n ^ 2 Ji Implementation of the algorithm and compare the same scale, the two kinds of algorithm' s time consuming.)
