Unitary polynomial

Let be a polynomial and be `maxroot` the maximal modulus of
the root of . From we may derive a polynomial such that the
roots of have a modulus lower or equal to 1 and if is a root
of then `maxroot` is a root of .
The calculation of the coefficients of may be done with the
procedure

int Unit_Polynom(int Degree,INTERVAL_VECTOR &Coeff,
double maxroot,INTERVAL_VECTOR &CoeffU)

where `Coeff` are the coefficients of and `CoeffU` the
coefficients of . This procedure returns 1 if the calculation has
been successfull, 0 otherwise.
