/**
* Class: mxEventObject
*
* The mxEventObject is a wrapper for all properties of a single event.
* Additionally, it also offers functions to consume the event and check if it
* was consumed as follows:
*
* (code)
* evt.consume();
* INV: evt.isConsumed() == true
* (end)
*
* Constructor: mxEventObject
*
* Constructs a new event object with the specified name. An optional
* sequence of key, value pairs can be appended to define properties.
*
* Example:
*
* (code)
* new mxEventObject("eventName", key1, val1, .., keyN, valN)
* (end)
