plot_vector_field takes two functions currently. I don't see any reason
it shouldn't be extended to take one function that returned two outputs,
though.
For now, at the cost of doing twice the computations, you could do
something like:
plot_vector_field((g_real(x,y), g_imag(x,y)), ...)
where g_real and g_imag return the real and imaginary parts of g(x,y)
