	//		This is an abstract API that data provider implementations conform to.
	//		This file defines methods signatures and intentionally leaves all the
	//		methods unimplemented.  For more information on the ,
	//		please visit: http://dojotoolkit.org/reference-guide/dojo/store.html
	//		Every method and property is optional, and is only needed if the functionality
	//		it provides is required.
	//		Every method may return a promise for the specified return value if the
	//		execution of the operation is asynchronous (except
	//		for query() which already defines an async return value).

	//		If the store has a single primary key, this indicates the property to use as the
	//		identity property. The values of this property should be unique.
	idProperty: "id",

	// queryEngine: Function
	//		If the store can be queried locally (on the client side in JS), this defines
	//		the query engine to use for querying the data store.
	//		This takes a query and query options and returns a function that can execute
	//		the provided query on a JavaScript array. The queryEngine may be replace to
	//		provide more sophisticated querying capabilities. For example:
	//		| var query = store.queryEngine({foo:"bar"}, {count:10});
	//		| query(someArray) -> filtered array
	//		The returned query function may have a "matches" property that can be
	//		used to determine if an object matches the query. For example:
	//		| query.matches({id:"some-object", foo:"bar"}) -> true
	//		| query.matches({id:"some-object", foo:"something else"}) -> false

	// before: Object?
	//		If the collection of objects in the store has a natural ordering,
	//		this indicates that the created or updated object should be placed before the
	//		object specified by the value of this property. A value of null indicates that the
	//		object should be last.
	// parent: Object?,
	//		If the store is hierarchical (with single parenting) this property indicates the
	//		new parent of the created or updated object.
	// overwrite: Boolean?
	//		If this is provided as a boolean it indicates that the object should or should not
	//		overwrite an existing object. A value of true indicates that a new object
	//		should not be created, the operation should update an existing object. A
	//		value of false indicates that an existing object should not be updated, a new
	//		object should be created (which is the same as an add() operation). When
	//		this property is not provided, either an update or creation is acceptable.

		//		- The object parameter indicates the object that was create, modified, or deleted.
		//		- The removedFrom parameter indicates the index in the result array where
		//		the object used to be. If the value is -1, then the object is an addition to
		//		this result set (due to a new object being created, or changed such that it
		//		is a part of the result set).
		//		- The insertedInto parameter indicates the index in the result array where
		//		the object should be now. If the value is -1, then the object is a removal
		//		from this result set (due to an object being deleted, or changed such that it
		//		is not a part of the result set).
		// includeAllUpdates:
		//		This indicates whether or not to include object updates that do not affect
		//		the inclusion or order of the object in the query results. By default this is false,
		//		which means that if any object is updated in such a way that it remains
		//		in the result set and it's position in result sets is not affected, then the listener
		//		will not be fired.

	//		property limiting the result set. This property indicates the total number of objects
