std::vector< std::pair< Index, int > > syten::Delinearise::calculate_scores	(	std::vector< DenseTensor< 1, Scalar > > const &	columns,
		std::vector< DenseTensor< 1, Scalar > > const &	thresh
	)

Calculates the zeroness score of all columns comparing against all others.

A columns zeroness score is the number of columns beat by this column minus the number of columns which beat this column. Column A beats column B

• if it has more exactly-zero thresholds (in thresh[A] and thresh[B] respectively)
• or, if tied, it has more exactly-zero values (in columns[A] and columns[B] respectively)
• or, if tied, it has more exactly-zero thresholds from the bottom in a row
• or, if tied, it has more exactly-zero values from the bottom in a row
