mysort.h include all kinds of sort algorithm and top N algorithm, namely bfpr algorithm.

mysearch.h is the binary search algorithm.

CSymbolFilter is a prefix filtering class implementation, namely so-called trie.

skiplist.h is one skiplist implementation and sliplist_test.cpp is the corresponding test file.
