findPolyRoots

<p>Finds real parts of polynomial's roots via eigendecomposition of companion
matrix. This method is not used by gaussHermiteData. Only the real parts of
each root are retained; this can be useful if the polynomial is known a
priori to have all roots real.</p>

Fast, numerically-stable Gauss-Hermite quadrature rules and
utility functions for adaptive GH quadrature. See Liu, Q. and Pierce, D. A.
(1994) <doi:10.2307/2337136> for a reference on these methods.
