Root locus diagram.

Calculate the root locus by finding the roots of 1 + k * G(s) where G
is a linear system with transfer function num(s)/den(s) and each k is
an element of kvect.
an element of gains.

Parameters
----------
sys : LTI object
Linear input/output systems (SISO only, for now).
kvect : array_like, optional
gains : array_like, optional
Gains to use in computing plot of closed-loop poles.
xlim : tuple or list, optional
Set limits of x axis, normally with tuple
