Detailed Description

template<class utPtr, class utCompare = std::less<utPtr>, bool need_changed_position = false>
class UT_PriorityQueue< utPtr, utCompare, need_changed_position >

NOTE: UT_PriorityQueue and std::priority_queue are max heaps, so the comparison direction must be opposite that for sorting an array.
