BinaryHeap
==========

Basic binary heap tree using linked lists

Usage
-----

``javascript
var BinaryHeap = require('binaryheap');
var heap = new BinaryHeap();

var a = [6, 5, 3, 1, 8, 7, 2, 4];

a.forEach(function (k) {
heap.insert({ value: k }, k);
});

heap.print();

while (heap.length) {
console.log('popping', heap.pop().value);
}
`

By default it stores as a max-heap, if you pass truthy to the constructor though
it will behave as a min-heap.

Methods
-------

* insert(obj, key) -- obj can be any new or existing object, and key is any
value that behaves sanely with > or <
* pop() -- removes and returns the maximum or minimum object from the root
of the heap
* remove(obj) -- removes a previously inserted object from the heap
* print() -- mostly for debugging purposes prints a graphviz dot style
digraph to confirm ordering

Members
-------

* length` -- number of objects currently in the heap
