 /** template class KeyedContainer, KeyedContainer.h
  *
  *  This class represents a container, where the contained objects
  *  are accessed by a key. Such a key can be any class, which is able
  *  to convert to and from a 32-bit (long) integer.
  *
  *  To insert objects into the container, this implementation
  *  determines the key in the following way:
  *  - If the object is already keyed, the object's key is kept
  *    and cannot be modified.
  *  - If the object is NOT keyed, and a key is supplied,
  *    this key is used to register the object in the map and
  *    the same key is given to the object.
  *  - If the object is NOT keyed, and NO key is supplied,
  *    a key is generated by the map implementation and this
  *    key is given to the object.
  *
  *  - It is not possible to insert two objects with the same key
  *    into the same container. This causes an exception.
  *
  *  Access to objects is given two-fold:
  *  - Using iterators. This access is very efficient. The container
  *    however, may not be manipulated: No objects may not be
  *    inserted or removed using iterators.
  *  - Using object keys: This access patterns provides random
  *    access to objects.
  *
  *  The KeyedContainer class uses for further specialization a traits
  *  class. By specializing these traits extra behaviour can be
  *  forced on request for special containers or special keys.
