//
// CLASS DESCRIPTION (MConditionMessage)
//
// This class is used to register callbacks for changes to specific
// conditions and/or to determine the current state of a condition.
//
// The addConditionCallback method allows callbacks to be registered
// for the following messages:
// Condition Changed
//
// The first parameter passed to the add callback method is the
// name of the condition that will trigger the callback. The names of
// available conditions can be retrieved with the getConditionNames
// method.
//
// Callbacks that are registered for conditions will be passed an
// bool parameter that is the state of the condition.
//
// Each method returns an id which is used to remove the callback.
//
// To remove a callback use MMessage::removeCallback.
//
// All callbacks that are registered by a plug-in must be removed by that
// plug-in when it is unloaded. Failure to do so will result in a fatal error.
//
// The getConditionState method is used to return the current status
// of the specified condition.
