 [Splay-tree](https://en.wikipedia.org/wiki/Splay_tree): **[fast](#benchmarks)**(non-recursive) and **simple**(< 1000 lines of code)
 Implementation is adapted directly from Wikipedia with the same API as [w8r/avl](https://github.com/w8r/avl), to run the benchmarks against other trees.
 
-
 This tree is based on **top-down** splaying algorithm by D.Sleator. It supports
- - splitting, merging
- - updating of the keys
- - bulk loading of the items into an empty or non-empty tree
- - insertion with duplicates or no duplicates
- - lookup without splaying

 ## API
 
-* `new SplayTree([comparator])`, where `comparator` is optional comparison function
-* `tree.insert(key:any, [data:any]):Node` - Insert item, allow duplicate keys
-* `tree.add(key:any, [data:any]):Node` - Insert item if it is not present
-* `tree.remove(key:any)` - Remove item
-* `tree.find(key):Node|Null` - Return node by its key
-* `tree.findStatic(key):Node|Null` - Return node by its key (doesn't re-balance the tree)
-* `tree.at(index:Number):Node|Null` - Return node by its index in sorted order of keys
-* `tree.contains(key):Boolean` - Whether a node with the given key is in the tree
-* `tree.forEach(function(node) {...}):Tree` In-order traversal
-* `tree.keys():Array<key>` - Returns the array of keys in order
-* `tree.values():Array<*>` - Returns the array of data fields in order
-* `tree.range(lo, high, function(node) {} [, context]):Tree` - Walks the range of keys in order. Stops, if the visitor function returns a non-zero value.
-* `tree.pop():Node` - Removes smallest node
-* `tree.min():key` - Returns min key
-* `tree.max():key` - Returns max key
-* `tree.minNode():Node` - Returns the node with smallest key
-* `tree.maxNode():Node` - Returns the node with highest key
-* `tree.prev(node):Node` - Predecessor node
-* `tree.next(node):Node` - Successor node
-* `tree.load(keys:Array<*>, [values:Array<*>][,presort=false]):Tree` - Bulk-load items. It expects values and keys to be sorted, but if `presort` is `true`, it will sort keys and values using the comparator(in-place, your arrays are going to be altered).

 **Comparator**
 
 `function(a:key,b:key):Number` - Comparator function between two keys, it returns
- * `0` if the keys are equal
- * `<0` if `a < b`
- * `>0` if `a > b`
 
- The comparator function is extremely important, in case of errors you might end
- up with a wrongly constructed tree or would not be able to retrieve your items.
- It is crucial to test the return values of your `comparator(a,b)` and `comparator(b,a)`
- to make sure it's working correctly, otherwise you may have bugs that are very
- unpredictable and hard to catch.

-* `insert()` method allows duplicate keys. This can be useful in certain applications (example: overlapping
