A class for finding the N roots of N one-dimensional non-linear equations.
The rational for making this class solve for the roots of N equations simultaneously is that, for some problems, it is more computationally efficient to evaluate the N equations at the same time, as opposed to one after the other. That is, the N equations, though decoupled, do share some common terms.
This class can always be used for a system where N=1, although there will be some small amount of overhead for this class to function in this way when compared to a class that is dedicated to an N=1.
To construct an instance of this class, the user must provide an instance of a VectorFunctionUncoupledNxN.
