New methods in PriorityQueue

[Roger Riggs]

Hi Julian,

Modifying the priorities of elements in the PriorityQueue violates the
invariants of the PriorityQueue established at insertion and maintained
at removal by the Comparator.

To maintain the invariant the element should be removed, its priority 
modified,
and re-inserted.

An API to manually manipulate the order is inconsistent with the design 
of PriorityQueue.

Regards, Roger
