                 zroots(a)

         returns the vector of (complex) roots of the (complex)
         polynomial: Sum(a(i)*x^(i-1)) using Laguerre's method.
         The roots are sorted in order of increasing real parts.  Call with
         non-zero imsort keyword to sort into increasing imaginary parts.
         See Numerical Recipes (Press, et. al., Cambridge Univ. Press 1988),
         section 9.5.
