/**
* @author Ed Spencer
* @class Ext.data.Errors
*
* <p>Wraps a collection of validation error responses and provides convenient functions for
* accessing and errors for specific fields.</p>
*
* <p>Usually this class does not need to be instantiated directly - instances are instead created
* automatically when {@link Ext.data.Model#validate validate} on a model instance:</p>
*
<pre><code>
//validate some existing model instance - in this case it returned 2 failures messages
var errors = myModel.validate();
errors.isValid(); //false
errors.length; //2
errors.getByField('name'); // [{field: 'name', message: 'must be present'}]
errors.getByField('title'); // [{field: 'title', message: 'is too short'}]
</code></pre>
