Idea from Eric Agol: allow exploration of hyperbolic orbits. This might be important in the Gaia era.
We currently use the Danby method to solve Kepler’s equation, but this only applies for e < 1. The paper below (Wisdom & Hernandez 2015) derives a more general solution that can be applied to hyperbolic and parabolic orbits.
