Clarify priority in PriorityQueue

[dpsanders]

Is the element with the largest or smallest priority first in the queue?

[dpsanders]

It seems to be the smallest priority:

julia> p = PriorityQueue(["a" => 5, "b" => 10, "c" => 15]);

julia> dequeue_pair!(p)
"a" => 5

[hdavid16]

It depends on the ordering direction (Forward or Reverse). The default is Forward, meaning the lowest value has the highest priority.

This can be closed as the documentation (now) clearly states that default ordering is min (Forward).
