template<class FR = FDRepr>
template<typename InputIterator>
void OutputBase< FR >::writeItemsetAndCounter (  InputIterator  first,

Writes out one itemset and its counter.

Parameters:
first An input iterator.
last An input iterator.
support the support of the itemset
The elements of the itemset are in the range [first, last).
