Added new classes for the implementation of concurrent greedy algorithms.
...
These classes can be used to produce an abstract worker process that can be used for common problems in artificial intelligence, such as game playing and problem solving. These classes will be used as abstraction layer for a new search process in YaCy. These classes had been created while searching for an abstraction of the current search process. It turned out that the abstraction of the YaCy search process is also an abstraction for problems in artificial intelligence and therefore the classes had been designed in such a way that it covers not only the YaCy-specific problem but also the more generic problems in ai. To test the classes they had been used in a ConnectFour implementation (game playing).
