     @version 
     @brief   Implements a dictionary for string variables.
  
     This module implements a simple dictionary object, i.e. a list
     of string/string associations. This object is useful to store e.g.
     informations retrieved from a configuration file (ini files).

    in the dictionary is speeded up by the use of a (hopefully collision-free)
    hash function.

    dictionary_get will return a NULL value: the variable will be found, and
    its value (NULL) is returned. In other words, setting the variable
    content to NULL is equivalent to deleting the variable from the
