Aho-Corasick Trie

易於使用Aho-Corasick Trie的實現。由所需的模式構建，然後可以處理文本，查找文本中包含的所有樣本。

示例彙編：

 g++ common.cpp ../Trie/Trie.cpp -o common

用法示例

    # include " Trie/Trie.hpp "

    ...

    Trie trie;
    set< int > found;
    char * patternsChar[] = {
        " Lorem " ,
        " lorem " ,
        " five centuries " ,
        " since the 1500s, when an unknown printer " ,
        " containing the Lorem "
    };
    vector<string> patterns (patternsChar, patternsChar + sizeof (patternsChar) / sizeof(patternsChar[ 0 ]));
    string text = " Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. " ;
    
    for ( size_t i = 0 ; i < patterns.size(); ++i) {
        trie. addPattern (patterns[i], i);
    }
    
    trie.processText(text, found);
    
    for (set< int >::iterator it = found.begin(); it != found.end(); it++) {
        cout << " Found pattern ( " << *it + 1 << " ): " << patterns[*it] << " . " << endl;
