^{2}Up to four iteration numbers can be specified. When only one is given, NCProcess uses that number to choose
default values for the other iteration numbers. If the user specifies four values, I_{1}, I_{2}, I_{3}, I_{4}, then I_{1} is the iterations
for NCMakeGB, I_{2} is the iterations for NCMakeGB on the digesteds, I_{3} is the iterations for SmallBasis, and I_{4} is the
iterations for the knowns in SmallBasis.
