bool GoUctDefaultPriorKnowledge::FindGlobalPatternAndAtariMoves	(	SgPointSet &	pattern,
		SgPointSet &	atari,
		GoPointList &	empty
	)			const

Find global moves that match a playout pattern or set a block into atari.

Parameters:

[out]	pattern
[out]	atari
[out]	empty	As a side effect, this function finds all empty points on the board

Returns:

true if any such moves was found
