/**
 * @class Ext.calendar.data.EventModel
 * @extends Ext.data.Record
 * <p>This is the {@link Ext.data.Record Record} specification for calendar event data used by the
 * {@link Ext.calendar.CalendarPanel CalendarPanel}'s underlying store. It can be overridden as 
 * necessary to customize the fields supported by events, although the existing column names should
 * not be altered. If your model fields are named differently you should update the <b>mapping</b>
 * configs accordingly.</p>
 * <p>The only required fields when creating a new event record instance are StartDate and
 * EndDate.  All other fields are either optional are will be defaulted if blank.</p>
 * <p>Here is a basic example for how to create a new record of this type:<pre><code>
rec = new Ext.calendar.data.EventModel({
    StartDate: '2101-01-12 12:00:00',
    EndDate: '2101-01-12 13:30:00',
    Title: 'My cool event',
    Notes: 'Some notes'
});
</code></pre>
 * If you have overridden any of the record's data mappings via the Ext.calendar.data.EventMappings object
 * you may need to set the values using this alternate syntax to ensure that the fields match up correctly:<pre><code>
var M = Ext.calendar.data.EventMappings;

rec = new Ext.calendar.data.EventModel();
rec.data[M.StartDate.name] = '2101-01-12 12:00:00';
rec.data[M.EndDate.name] = '2101-01-12 13:30:00';
rec.data[M.Title.name] = 'My cool event';
rec.data[M.Notes.name] = 'Some notes';
</code></pre>
 * @constructor
 * @param {Object} data (Optional) An object, the properties of which provide values for the new Record's
 * fields. If not specified the {@link Ext.data.Field#defaultValue defaultValue}
 * for each field will be assigned.
 * @param {Object} id (Optional) The id of the Record. The id is used by the
 * {@link Ext.data.Store} object which owns the Record to index its collection
 * of Records (therefore this id should be unique within each store). If an
 * id is not specified a {@link #phantom}
 * Record will be created with an {@link #Record.id automatically generated id}.
