[xwitkgjv] Interstellar transport network

Extend the low energy Interplanetary Transport Network for interstellar transport.

Idea: use the IPTN to get to a Sun-Jupiter Lagrange point, and use that to launch out of the solar system to Alpha Centauri. Use the binary star system of Alpha Centauri to launch to anywhere (Because of its binary nature, I'm guessing it has Lagrange-like unstable points.)

Or, further away, the white dwarves Sirius B or Procyon B offer extremely deep gravitational wells for powerful slingshots.
