Priority Queue Dictionary (pqdict)
==================================
A priority queue dictionary maps hashable objects (keys) to priority-determining values. It provides a hybrid dictionary/priority queue API.

The priority queue is implemented as a binary heap of (key, priority value)
pairs, which supports:
- O(1) search for the item with highest priority
- O(log n) removal of the item with highest priority
- O(log n) insertion of a new item
Additionally, an index maps elements to their location in the heap and is kept
up to date as the heap is manipulated. As a result, pqdict also supports:
- O(1) lookup of any item by key
- O(log n) removal of any item
- O(log n) updating of any item's priority level
