/**
* A FormHandler can be registered with a {@link org.apache.cocoon.forms.formmodel.Form Form},
* and will then receive all events fired by widgets on the form.
*
* <p>It provides an alternative way of handling events, instead of specifying the eventhandlers
* in the form definition.
*
* <p>It is useful when you want to write your event-handling code in Java, have all events
* handled by one class (which could of course again delegate to other classes), and when
* you want the event handler to have access to objects it would not be able to get access
* to if they were part of the form definition.
