Overview
========
Backbone.Shard is a variation on a Subset taken from different perspective.
Shard was built as a simple "persistent filter" for collections; it can
help grouping and displaying items of certain kind based on your filter
function. I know it works for me, but your mileage may vary.
Usage
=====
It's easy if you're familiar with Backbone.Collection since Shard shares
with it most of the methods marked **Underscore methods** in the
[documentation](http://backbonejs.org/#Collection-Underscore-Methods):
:::javascript
var shelf = Backbone.Shard({
collection: books,
filter: function(book) { return book.get('read'); }
});
shelf.each(...);
shelf.pluck(...);
You can add/remove models or reset *the original collection* and Shard will
honestly try to keep up with it, but currently Shard itself has no methods
such as add/remove/reset.
Events work and respect your filter function:
:::javascript
shelf.on('add', doSomething);
collection.add({read true}); // this will call doSomething
collection.add({read: false}); // this won't
