pair< hashtype, vector< int > > Algo_hash_corner::compute_hashkey	(	PatternList &	pl,
		int	CS
	)

virtual

Given a PatternList and a choice of colorSwitch (true/false), compute the hashCodes that we have to look for in the db.

The method returns a vector of pairs, consisting of a hashCode (for one of the corners covered by the pattern) and a vector of possible flips which should be used to produce a Candidate.

Reimplemented from Algo_hash.
