## Description

Allows performing chunked queries on DataMapper Models or Collections.

## Features

* Allows random-access to chunks within a query.
* Can iterate through all chunks within a query.
* Can be used for bulk-processing of resources.
* Can also be used for pagination of resources.

## Examples

Enumerate over all chunks, 20 resources per-chunk:

    require 'dm-chunked_query'

    MyModel.chunks(20).each do |chunk|
      chunk.each do |resource|
        # ...
      end
    end

Get the 5th chunk, containing 10 resources:

    MyModel.all(:foo => 'bar').chunks(10)[5]
