Parameters:

	score_a	score vector (typically c(1,1,...,1))
	score_b	score vector (typically ranks)
	m_a	integer indicating the sum of m_a elements of score_a
	m_b	integer indicating the sum of m_b elements of score_b
	retProb	logical indicating whether the density (TRUE) or the matrix of all permutations should be returned
