summary.FCVAR_roots
prints the output of
GetCharPolyRoots
to screen.
GetCharPolyRoots
calculates the roots of the
characteristic polynomial to plot them with the unit circle
transformed for the fractional model, see Johansen (2008).

The roots are calculated from the companion form of the VAR, where the roots are given as the inverse eigenvalues of the coefficient matrix.
