#Spinal Queue Spec
This specification declares the interface for the "spinal" queue in `PowerQueue`.
We allready have two implementations the [MicroQueue](https://github.com/zcfs/Meteor-micro-queue) and [ReactiveList](https://github.com/zcfs/Meteor-reactive-list)

#SpinalQueue
Provides a simple reactive list interface

#### <a name="SpinalQueue"></a>new SpinalQueue(lifo)&nbsp;&nbsp;<sub><i>Anywhere</i></sub> ####
-

__Arguments__

* __lifo__ *{boolean}*
Set the order of the queue default is `fifo`

-
Example:
```js
  var list = new SpinalQueue();
  list.insert(1, { text: 'Hello id: 1' });
  list.insert(2, { text: 'Hello id: 2' });
  list.insert(3, { text: 'Hello id: 3' });
  list.update(2, { text: 'Updated 2'});
  list.remove(1);
  
  list.forEach(function(value, key) {
    console.log('GOT: ' + value.text);
  }, true); // Set noneReactive = true, default behaviour is reactive
  // Return from Template:
  Template.hello.list = function() {
    return list.fetch();
  };
```
