tableau, which adaptively increases the degree of an extrapolation polynomial
until convergence is achieved to a desired tolerance (or convergence stalls
due to e.g. floating-point errors).  This allows one to obtain @code{f(x0)} to
high-order accuracy, assuming that @code{f(x0+h)} has a Taylor series or some
other power series in @code{h}.")
