    Random Generator service interface definition
    Definition of a interface for a service to access
    random generators according to predefined distributions:

    The Random Generator creates proper instances of requested
    random generators and delivers them to the user.

    On request the service dumps the type and state of the random
    number engine to a StreamBuffer object allowing to save and to restore
    the exact state of the random number generator.
