Modified files:
	src            : Row.defs.hh Row.cc Matrix.cc minimize.cc 
	                 simplify.cc 

Log message:
	Strong normalization of Row objects now enforce the first non-zero coefficient
	to be positive.
	When creating a matrix having n copies of the same row, the matrix is now
	declared to be sorted (since sortedness by itself does not implies that it
	has no duplicates); this also includes the case of empty matrices.
	Some improvements in methods Matrix::gauss() and Matrix::back_substitute().
