/**
 * @class Ext.MasterTemplate
 * @extends Ext.Template
 * Provides a template that can have child templates. The syntax is:
<pre><code>
var t = new Ext.MasterTemplate(
        '&lt;select name="{name}"&gt;',
                '&lt;tpl name="options"&gt;&lt;option value="{value:trim}"&gt;{text:ellipsis(10)}&lt;/option&gt;&lt;/tpl&gt;',
        '&lt;/select&gt;'
);
t.add('options', {value: 'foo', text: 'bar'});
// or you can add multiple child elements in one shot
t.addAll('options', [
    {value: 'foo', text: 'bar'},
    {value: 'foo2', text: 'bar2'},
    {value: 'foo3', text: 'bar3'}
]);
// then append, applying the master template values
t.append('my-form', {name: 'my-select'});
</code></pre>
* A name attribute for the child template is not required if you have only one child
* template or you want to refer to them by index.
