Double-ended priority queues
This library provides a type for 'DEPQ's, along with functions for constructing and querying them.
Usage
The Data.DEPQ module exports the user interface, which is similar to that of most Haskell data container libraries.
Populate a DEPQ (either from a Foldable collection such as a list or array or by inserting incrementally) and query either of its extremes (with findMin, findMax, popMin, popMax, topK, bottomK).
Have fun!
Implementation
Currently the implementation is based on 'IntPSQ' (integer-indexed priority search queues) from the 'psqueues' package.
