Estimate radius of convergence of a real-valued Taylor series from its coefficients when convergence is limited by singularities.

Estimate radius of convergence of a real-valued Taylor
series from its coefficients when convergence is limited
by either a real singularity or a complex conjugate pair
of singularities. Execute with no argument to see an
example. Also estimate the location and nature of the
singularities---assuming they are of form [z-r]^nature or
[z-r*exp(i*theta)]^nature. See Appendix of the article by
Mercer & Roberts (1990) "A centre manifold description of
contaminant dispersion in channels with varying flow
