Minterms

Usage:
	minterms(num_terms, sigma_size, sigma ...)

	where:	
		num_terms is the number of variables

		sigma_size is the amount of minterms to follow

		sigma is all the rest of arguments given used to make an array of required minterms

	more simply:
		sigma_size = the total number of arguments - the first two
		so for minterms(4, sigma_size, 1,2,3,4,5) sigma_size must equal 5

	the return value is a string of the binary function
	
	for instance minterms(4,2,0,1) = -a*-b*-c*-d+-a*-b*-c*d
	4 variables 'a','b','c','d'
	2 arguments to follow
	minterm 0 -a*-b*-c*-d
	minterm 1 -a*-b*-c*d
