几个库DGL、STL(vc6)、STL(SGI)、DCL 、DeCal、EZDSL的容器性能对比测试
DGL库的实际实现性能在很多方面接近了最有名的STL实现: SGI STL ！
(2006.10.20 DGL Profiler
DGL添加红黑树，增加容器:_TMap/_TMultiMap/_TSet/_TMultiSet;
更新DeCal和EZDSL的Hash表测试，由于它们不支持动态调整大小所以造成以前的测试成绩不能反映真实情况；
测试Visite或Find的时候会同时测试读和写，如果不能写，就读两次
DGL和STL使用了相同的测试，测试数据集1000万个integer;选用integer能够更好地反映库的性能；
(某些Delphi库使用string的测试成绩来说自己的库比STL的快完全是误导，这完全是由string的不同实现导致的)；
其他几个库的测试，如果库的性能比较差，就会采取减小测试数据集的办法来减少测试时间；
对于线性容器(vector/deque/list)的随机访问使用了1M个integer;
