21///This class displays a graphical interface to set up
22///and run different algorithms. Different algorithms need
23///different inputs, running methods, etc. Therefore
24///class \ref AlgoWin is only a holder of a base class, the so
25///called AlgoBox. \ref AlgoBox is the ancestor of other
26///classes. These child classes realize interfaces of different
27///algorithms, but as their common ancestor is \ref AlgoBox
28///the interface of them is the same. \ref AlgoWin communicates
29///with these classes through this common interface. But it the
30///real object to be placed in \ref AlgoWin depends on the algorithm
31///which the \ref AlgoWin actually has to display. It gets the
32///id of algorithm to display at initialization, and therefore it is
33///able to place in itself the requested child of \ref AlgoBox
34/// visualizing the appropriate algorithm.
