/**
 *
 * This mixin can be used on a DS.Model to add a `saveBulk` function.
 *
 * Saving a lot of data at the same time can be quite inefficient. To solve this issue, you can use the provided `model-bulk-save` mixin on your ember-data models:
 *
 * ```js
 *import DS from 'ember-data';
 *import ModelBulkSaveMixin from 'ember-indexeddb/mixins/model-bulk-save';
 *
 *export default DS.Model.extend(ModelBulkSaveMixin, {
 *  name: DS.attr('string')
 *});
 * ```
 *
 * Now, this model will have a new function `bulkSave()`:
 *
 * ```js
 *let promise1 = model1.saveBulk();
 *let promise2 = model2.saveBulk();
 * ```
 *
 * In the above example, `promise1` and `promise2` would actually be the same promise, and both of these items would be saved in one transaction. This waits for 100ms before resolving,  * so every model that calls `saveBulk` in this time period will be saved in the same transactions. Note that this function will resolve with all the saved objects.
 *
 * @module Ember Data
 * @class ModelBulkSave
 * @extends Ember.Mixin
 * @private
