Description: 程序说明：
Form1.cs是应用聚类算法DBSCAN (Density-Based Spatical Clustering of Application with Noise)的示例，可以通过两个参数EPS和MinPts调节聚类。
DBSCAN.cs是实现文件，聚类算法的进一步信息请参考“数据挖掘”或者相关书籍
聚类示例数据来自于sxdb.mdb，一个Access数据库。
已知问题及进一步改进建议：
问题：dbscan.cs行64，SortedList不支持重复键，因此若两个数据点距离相同则无法加入集合
解决：采用人为减小一个微小量，使数据点距离不同且不影响聚类结果
上一解决方案的问题：减小double.Epsilon微小量无助于使SortedList认为两点距离以及不同
解决：采用一个指数增长的微小量，连续重试直至SortedList认为距离已经不同
进一步改进建议：可能通过double的强制转型为内存中的byte类型（假设double型转为8个byte）
然后最后一个byte减去0x01可比较漂亮的解决问题，但是……呵呵，C#中我不会这个操作
也可以自己实现一个SortedList，支持重复键，当然，这，好像是微软应该做的工作了 ^_^

Description: Density-Based Spatial Clustering of Applications with Noise (or DBSCAN) is an algorithm used in cluster analysis which is described in this Wikipedia article (http://en.wikipedia.org/wiki/DBSCAN).
The basic idea of cluster analysis is to partition a set of points into clusters which have some relationship to each other. In the case of DBSCAN the user chooses the minimum number of points required to form a cluster and the maximum distance between points in each cluster. Each point is then considered in turn, along with its neighbours, and allocated to a cluster.
