 * by an {@link Ext.data.Store}.  This class is intended to be extended and should not
 * be created directly. For existing implementations, see {@link Ext.data.ArrayReader},
 * {@link Ext.data.JsonReader} and {@link Ext.data.XmlReader}.
 * @constructor Create a new DataReader
 * @param {Object} meta Metadata configuration options (implementation-specific)
 * @param {Object} recordType Either an Array of field definition objects as specified
 * in {@link Ext.data.Record#create}, or an {@link Ext.data.Record} object created
 * using {@link Ext.data.Record#create}.
