A Backbone collection with paging and simple caching capabilities
var collection = new Backbone.PagedCollection(models, [options]);
PagedCollection accepts the same options as Backbone.Collection, with the following additions:
perPage: number of items to display per page, defaults to 10.
collection: type of collection to use as the page collection, defaults to Backbone.Collection.
There's an optional collection.filter() function, which accepts an object of key-values, resets the collection and passes the filter object as the data in the Backbone.sync requests.
PagedCollection expects server responses to be of the following format:
{
total: [total],
per_page: [per_page],
page: [current_page],
items: [array_of_items]
}
