-/// MovePicker is a class which is used to pick one pseudo legal move at a time

-/// moves we have reason to believe are good. The most important method is
-/// MovePicker::get_next_move(), which returns a new pseudo legal move each time
-/// it is called, until there are no moves left, when MOVE_NONE is returned.
-/// In order to improve the efficiency of the alpha beta algorithm, MovePicker
-/// attempts to return the moves which are most likely to get a cut-off first.
