Detailed Description

   template<bool stable, typename T, typename Comparator>class __gnu_parallel::LoserTree< stable,
       T, Comparator >
       Stable LoserTree variant.

       Provides the stable implementations of insert_start, init_winner, init and
       delete_min_insert.

       Unstable variant is done using partial specialisation below.

   template<bool stable, typename T , typename Comparator > void __gnu_parallel::LoserTree<
       stable, T, Comparator >::delete_min_insert (Tkey, boolsup) [inline]
       Delete the smallest element and insert a new element from the previously smallest
       element's sequence. This implementation is stable.

   template<typename T , typename Comparator > int __gnu_parallel::LoserTreeBase< T, Comparator
       >::get_min_source () [inline],  [inherited]
       Returns:
           the index of the sequence with the smallest element.

   template<typename T , typename Comparator > void __gnu_parallel::LoserTreeBase< T, Comparator
       >::insert_start (const T &key, intsource, boolsup) [inline],  [inherited]
       Initializes the sequence 'source' with the element 'key'.

       Parameters:
           key the element to insert
           source index of the source sequence
           sup flag that determines whether the value to insert is an explicit supremum.
