 1/**
 2 * @example Simple Store
 3 *
 4 * This example creates a simple store that auto-loads its data from an ajax
 5 * proxy. Since we are only dealing with data there is no UI, so a global
 6 * variable called "userStore" is created which is an instance of
 7 * {@link Ext.data.Store}.
 8 *
 9 * Feel free to experiment with the "userStore" object on the console command
10 * line. For example - `userStore.getCount()` gets the total number of records
11 * in the store. `userStore.getAt(0)` gets the record at index 0.
