本代码提供对动态数组的支持，在内存中程序将数据分块存放，避免了大块内存的申请。同时，与普通的双向链表不同，本代码提供了对内部数据的快速索引，大大提高了数据访问速度-The code provides for dynamic array support program in memory data block storage, to avoid the large memory applications. At the same time, with ordinary two-way different list, the source of internal data to provide rapid indexing, greatly improving the speed of data access
