Static Public Member Functions
static const LookupTablePtr	aggregate (const std::string &result_lookup_table_name, const LookupTable &lookup_table, const LookupColumn &lookup_col)
	aggregates LookupTable wrt Lookup Column, which indexes the LookupTable. IT takes care of copying the LookupColumns and their corresponding PostitionList. Furthermore, it calls functions which createa new LookupArraylist, which represents the columns of the Table (a view, to be more precise) represented by the Lookup Table
