-<pre><code>
-Ext.define('User', {

-*
-* <p>The fields array is turned into a {@link Ext.util.MixedCollection MixedCollection} automatically by the {@link Ext.ModelManager ModelManager}, and all
-* other functions and properties are copied to the new Model's prototype.</p>
-*
-* <p>Now we can create instances of our User model and call any model logic we defined:</p>
-*
-<pre><code>
-var user = Ext.ModelManager.create({
- name : 'Conan',
- age : 24,
- phone: '555-555-5555'
-}, 'User');
-
-user.changeName();
-user.get('name'); //returns "Conan The Barbarian"

- * <p>Models can have associations with other Models via {@link Ext.data.BelongsToAssociation belongsTo} and
