/** \class EventObject
* \brief Abstraction of the Events used to communicating among filters
and with GUIs.
*
* EventObject provides a standard coding for sending and receiving messages
* indicating things like the initiation of processes, end of processes,
* modification of filters.
*
* EventObjects form a hierarchy similar to the itk::ExceptionObject allowing
* to factorize common events in a tree-like structure. Higher detail can
* be assigned by users by subclassing existing itk::EventObjects.
*
* EventObjects are used by itk::Command and itk::Object for implementing the
* Observer/Subject design pattern. Observers register their interest in
* particular kinds of events produced by a specific itk::Object. This
* mechanism decouples classes among them.
*
* As opposed to itk::Exception, itk::EventObject does not represent error
* states, but simply flow of information allowing to trigger actions
* as a consequence of changes occurring in state on some itk::Objects.
*
* itk::EventObject carries information in its own type, it relies on the
* appropriate use of the RTTI (Run Time Type Information).
*
* A set of standard EventObjects is defined near the end of itkEventObject.h.
