  /**
  * @class Ext.data.Record
   * <p>Instances of this class encapsulate both Record <em>definition</em> information, and Record
   * <em>value</em> information for use in {@link Ext.data.Store} objects, or any code which needs
   * to access Records cached in an {@link Ext.data.Store} object.</p>
   * <p>Constructors for this class are generated by passing an Array of field definition objects to {@link #create}.
   * Instances are usually only created by {@link Ext.data.Reader} implementations when processing unformatted data
   * objects.</p>
   * <p>Note that an instance of a Record class may only belong to one {@link Ext.data.Store Store} at a time.
   * In order to copy data from one Store to another, use the {@link #copy} method to create an exact
   * copy of the Record, and insert the new instance into the other Store.</p>
   * <p>When serializing a Record for submission to the server, be aware that it contains many private
   * properties, and also a reference to its owning Store which in turn holds references to its Records.
   * This means that a Record may not be encoded using {@link Ext.util.JSON.encode}. Instead, use the
   * {@link data} and {@link id} properties.</p>
   * Record objects generated by this constructor inherit all the methods of Ext.data.Record listed below.
   * @constructor
   * This constructor should not be used to create Record objects. Instead, use the constructor generated by
   * {@link #create}. The parameters are the same.
   * @param {Array} data An object, the properties of which provide values for the new Record's fields.
   * @param {Object} id (Optional) The id of the Record. This id should be unique, and is used by the
   * {@link Ext.data.Store} object which owns the Record to index its collection of Records. If
   * not specified an integer id is generated.

  /**
   * Generate a constructor for a specific Record layout.
   * @param {Array} o An Array of field definition objects which specify field names, and optionally,
   * data types, and a mapping for an {@link Ext.data.Reader} to extract the field's value from a data object.
   * Each field definition object may contain the following properties: <ul>
   * <li><b>name</b> : String<div class="sub-desc">The name by which the field is referenced within the Record. This is referenced by,
   * for example, the <em>dataIndex</em> property in column definition objects passed to {@link Ext.grid.ColumnModel}</div></li>
   * <li><b>mapping</b> : String<div class="sub-desc">(Optional) A path specification for use by the {@link Ext.data.Reader} implementation
   * that is creating the Record to access the data value from the data object. If an {@link Ext.data.JsonReader}
   * is being used, then this is a string containing the javascript expression to reference the data relative to
   * the Record item's root. If an {@link Ext.data.XmlReader} is being used, this is an {@link Ext.DomQuery} path
   * to the data item relative to the Record element. If the mapping expression is the same as the field name,
   * this may be omitted.</div></li>
   * <li><b>type</b> : String<div class="sub-desc">(Optional) The data type for conversion to displayable value. Possible values are
   * <ul><li>auto (Default, implies no conversion)</li>
   * <li>string</li>
   * <li>int</li>
   * <li>float</li>
   * <li>boolean</li>
   * <li>date</li></ul></div></li>
   * <li><b>sortType</b> : Function<div class="sub-desc">(Optional) A function which converts a Field's value to a comparable value
   * in order to ensure correct sort ordering. Predefined functions are provided in {@link Ext.data.SortTypes}.</div></li>
   * <li><b>sortDir</b> : String<div class="sub-desc">(Optional) Initial direction to sort. "ASC" or "DESC"</div></li>
   * <li><b>convert</b> : Function<div class="sub-desc">(Optional) A function which converts the value provided
   * by the Reader into an object that will be stored in the Record. It is passed the
   * following parameters:<ul>
   * <li><b>v</b> : Mixed<div class="sub-desc">The data value as read by the Reader.</div></li>
   * <li><b>rec</b> : Mixed<div class="sub-desc">The data object containing the row as read by the Reader.
   * Depending on Reader type, this could be an Array, an object, or an XML element.</div></li>
   * </ul></div></li>
   * <li><b>dateFormat</b> : String<div class="sub-desc">(Optional) A format string for the {@link Date#parseDate Date.parseDate} function,
   * or "timestamp" if the value provided by the Reader is a UNIX timestamp, or "time" if the value provided by the Reader is a 
   * javascript millisecond timestamp.</div></li>
   * <li><b>defaultValue</b> : Mixed<div class="sub-desc">(Optional) The default value used <b>when a Record is being created by a
   * {@link Ext.data.Reader Reader}</b> when the item referenced by the <b><tt>mapping</tt></b> does not exist in the data object
   * (i.e. undefined). (defaults to "")</div></li>
   * </ul>
   * The constructor generated by this method may be used to create new Record instances. The data object must contain properties
   * named after the field <b>names</b>.
