Node position (lat,lng and vector), node periapsis/apoapsis eta

[adammada]

I'm doing "node-driven" kOS script ( http://forum.kerbalspaceprogram.com/threads/58068-kOS-The-Automated-Mission-Challenge?p=798117&viewfull=1#post798117 ).

And i'm limited by lack of few things:

• I need position of Node (relative to surface of body, by giving lat and lang, and as Vector).
  It would be really powerfull, for example when i want to enter equatorial orbit i have no way of testing it by using nodes. With node position i could just add node after periapsis and check it Latitude. Also moving nodes to correct ejection angles would be possible with that.

Also eta to node periapsis/apoapsis would help (for example to add mid-course burn). You could add position of periapsis/apoapsis just like to node. (of course, having node periapsis eta would allow to create node there and read it position, but would be better to have both).
