  // Purpose:     Single hashed Map. This  Map is used  to store and
  //              retrieve keys in linear time.
  //              The ::Iterator class can be  used to explore  the
  //              content of the map. It is not  wise to iterate and
  //              modify a map in parallel.
  //              To compute  the hashcode of  the key the  function
  //              ::HashCode must be defined in the global namespace
  //              To compare two keys the function ::IsEqual must be
  //              defined in the global namespace.
  //              The performance of  a Map is conditioned  by  its
  //              number of buckets that  should be kept greater  to
  //              the number   of keys.  This  map has  an automatic
  //              management of the number of buckets. It is resized
  //              when  the number of Keys  becomes greater than the
  //              number of buckets.
  //              If you have a fair  idea of the number of  objects
  //              you  can save on automatic   resizing by giving  a
  //              number of buckets  at creation or using the ReSize
  //              method. This should be  consider only for  crucial
  //              optimisation issues.
