CTimeStampMemoizer  Aim: A generic class to store a given maximum number of pairs (key, value). The class tends to memorize pairs which are accessed more frequently than others. It is thus a memoizer, which is used to memorize the result of costly computations. The memoization principle is simple: a timestamp is attached to a pair (key,value). Each time a query is made, if the item was memoized, the result is returned while the timestamp of the item is updated. User can also add or update a value in the memoizer, which updates also its timestamp. After adding a pair (key,value), if the maximal number of items is reached, at least the oldest half (or a fraction) of the items are deleted, leaving space for storing new pairs (key,value)
