npm install bintreesBinary Trees 
============
This package provides Binary and Red-Black Search Trees written in Javascript. It is released under the MIT License.
Binary Search Trees are a good way to store data in sorted order. A Red-Black tree is a variation of a Binary Tree that balances itself.
Algorithms were taken from Julienne Walker: http://eternallyconfuzzled.com/jsw_home.aspx
Trees
------------
* BinTree - Binary Search Tree
* RBTree - Red-Black Tree
Quickstart
------------
node.js:
```
npm install bintrees
`javascript
var RBTree = require('bintrees').RBTree;
var tree = new RBTree(function(a, b) { return a - b; });
tree.insert(2);
tree.insert(-3);
`
see examples/node.js for more info
In the browser:

see examples/client.html for more info
Constructor
------------
Requires 1 argument: a comparator function f(a,b) which returns:
* 0 if a == b
* >0 if a > b
* <0 if a < b
Methods
------------
Iterators
------------
tree.iterator() will return a null-iterator. On a null iterator,
* next() will return the first element in the tree
* prev() will return the last element in the tree
Otherwise,
* next() will return the next element
* prev() will return the previous element
* data() will return the node the iterator is pointing to
When iteration reaches the end, the iterator becomes a null-iterator again.
Forward iteration example:
`javascript``
var it=tree.iterator(), item;
while((item = it.next()) !== null) {
// do stuff with item
}
If you are iterating forward through the tree, you can always call prev() to go back, and vice versa.
__NOTE:__ iterators become invalid when you add or remove elements from the tree.
