EventDataWrapper

This class implements the Mathworks suggestion for adding custom data to events (see http://www.mathworks.com/help/matlab/matlab_oop/events-and-listeners--syntax-and-techniques.html#brb6i_k). It is intended to make custom event data more convenient. User-defined fields and values are provided as key-value pairs to the class constructor.
Example:
>> evt = Utilities.EventDataWrapper('key1',val1,'key2',val2,...);
>> notify(obj,'EventName',evt);

The download files include a complete example of an event with custom data.
