+	//	pattern: string
+	//		A simple matching pattern to convert that follows basic rules:

+	//			? Means match single character.  So, b?b will match to bob and bab, and so on.
+	//      	\ is an escape character.  So for example, \* means do not treat * as a match, but literal character *.
+	//				To use a \ as a character in the string, it must be escaped.  So in the pattern it should be 
+	//				represented by \\ to be treated as an ordinary \ character instead of an escape.
+	//
+	//	ignoreCase:
+	//		An optional flag to indicate if the pattern matching should be treated as case-sensitive or not when comparing
+	//		By default, it is assumed case sensitive.

+	//		The simpleFetch mixin is designed to serve as a set of function(s) that can
+	//		be mixed into other datastore implementations to accelerate their development.  
+	//		The simpleFetch mixin should work well for any datastore that can respond to a _fetchItems() 
+	//		call by returning an array of all the found items that matched the query.  The simpleFetch mixin
+	//		is not designed to work for datastores that respond to a fetch() call by incrementally
+	//		loading items, or sequentially loading partial batches of the result
+	//		set.  For datastores that mixin simpleFetch, simpleFetch 
+	//		implements a fetch method that automatically handles eight of the fetch()
+	//		arguments -- onBegin, onItem, onComplete, onError, start, count, sort and scope
+	//		The class mixing in simpleFetch should not implement fetch(),
+	//		but should instead implement a _fetchItems() method.  The _fetchItems() 
+	//		method takes three arguments, the keywordArgs object that was passed 
+	//		to fetch(), a callback function to be called when the result array is
+	//		available, and an error callback to be called if something goes wrong.
+	//		The _fetchItems() method should ignore any keywordArgs parameters for
+	//		start, count, onBegin, onItem, onComplete, onError, sort, and scope.  
+	//		The _fetchItems() method needs to correctly handle any other keywordArgs
+	//		parameters, including the query parameter and any optional parameters 
+	//		(such as includeChildren).  The _fetchItems() method should create an array of 
+	//		result items and pass it to the fetchHandler along with the original request object 
+	//		-- or, the _fetchItems() method may, if it wants to, create an new request object 
+	//		with other specifics about the request that are specific to the datastore and pass 
+	//		that as the request object to the handler.

+	//		For more information on this specific function, see dojo.data.api.Read.fetch()
