+/*! \file CbcEventHandler.hpp
+    \brief Event handling for cbc
+
+  This file contains the declaration of CbcEventHandler, used for event
+  handling in cbc.
+
+  The central method is CbcEventHandler::event(). The default semantics of
+  this call are `ask for the action to take in reponse to this event'. The
+  call is made at the point in the code where the event occurs (<i>e.g.</i>,
+  when a solution is found, or when a node is added to or removed from the
+  search tree). The return value specifies the action to perform in response
+  to the event (<i>e.g.</i>, continue, or stop).
+
+  This is a lazy class. Initially, it knows nothing about specific events,
+  and returns dfltAction_ for any event. This makes for a trivial constructor
+  and fast startup. The only place where the list of known events or actions
+  is hardwired is in the enum definitions for CbcEvent and CbcAction,
+  respectively.
+
+  At the first call to setAction, a map is created to hold (Event,Action)
+  pairs, and this map will be consulted ever after. Events not in the map
+  will still return the default value.
+
+  For serious extensions, derive a subclass and replace event() with a
+  function that suits you better.  The function has access to the CbcModel
+  via a pointer held in the CbcEventHandler object, and can do as much
+  thinking as it likes before returning an answer.  You can also print as
+  much information as you want. The model is held as a const, however, so
+  you can't alter reality.
+
+  The design of the class deliberately matches ClpEventHandler, so that other
+  solvers can participate in cbc without breaking the patterns set by
+  clp-specific code.

+/*! \class CbcEventHandler
+    \brief Base class for Cbc event handling.
+
+  Up front: We're not talking about unanticipated events here. We're talking
+  about anticipated events, in the sense that the code is going to make a call
+  to event() and is prepared to obey the return value that it receives.
+
+  The general pattern for usage is as follows:
+  <ol>
+    <li> Create a CbcEventHandler object. This will be initialised with a set
+	 of default actions for every recognised event.
+
+    <li> Attach the event handler to the CbcModel object.
+
+    <li> When execution reaches the point where an event occurs, call the
+	 event handler as CbcEventHandler::event(the event). The return value
+	 will specify what the code should do in response to the event.
+  </ol>
+
+  The return value associated with an event can be changed at any time.
