:mrdocs:

Create a priority queue from the elements of the specified `range`. Optionally specify a `comparator` used to order elements in the priority queue. Optionally supply an `allocator` to supply memory. If `allocator` is not supplied and if `CONTAINER` is allocator aware, the currently installed default allocator is used. Note that `range` must (minimally) meet the requirements of an input range and the values from the range must have a type matching or convertible to (template parameter) `VALUE`. Also note that the constructor overloads that take allocators are defined only if the underlying `CONTAINTER` is allocator aware.
