In a technical paper, the author introduces a sequential ARM algorithm,SEAR,to
the reader.
"Andreas Mueller's Sequential Efficient Association Rules algorithm is 
identical to Apriori, except that SEAR stores candidates in a prefix tree

instead of a hash tree. In a prefix tree(also called trie), each edge is
labeled by items; common prefixes are represented by tree branches, and 
the unique suffixes are stored at the leaves. Also,SEAR uses a pass-bundling
