// The Observable store wrapper takes a store and sets an observe method on query()
// results that can be used to monitor results for changes.
//
// description:
// Observable wraps an existing store so that notifications can be made when a query
// is performed.
//
// example:
// Create a Memory store that returns an observable query, and then log some
// information about that query.
//
// | var store = dojo.store.Observable(new dojo.store.Memory({
// | data: [
// | {id: 1, name: "one", prime: false},
// | {id: 2, name: "two", even: true, prime: true},
// | {id: 3, name: "three", prime: true},
// | {id: 4, name: "four", even: true, prime: false},
// | {id: 5, name: "five", prime: true}
// | ]

// | var observer = results.observe(function(object, previousIndex, newIndex){
// | changes.push({previousIndex:previousIndex, newIndex:newIndex, object:object});
