\subsection{Detailed Description}
\subsubsection*{template$<$class PP, typename MP, typename PAT\_\-ST, template$<$ typename, typename, typename $>$ class CC$>$ class tokenizer$<$ ISET\_\-PATTERN $>$}

Itemset tokenizer class by partial specialization of the generic tokenizer class. 

the template argument is instantiated with a pattern that has no\_\-edge pattern property, Fk X Fk and vert\_\-mine mining property, PAT\_\-ST type of pattern storage and CC type of canocial code.
