Thanks djungelorm for this great mod!
I used it for learning my first programming language (Java). I created an library that could be seen as an extension to yours. Because this is the first real software I have created, it could be that it is an over engineered clusterlove, but its working, which is nice. If someone wants to try it -> here is the link to the source code and precomiled libraries and executables.
It basically is an "autopilot" that can launch your vessel into an desired orbit around the planet. It also can be used as a library for other projects providing methods for getting the deltaV of any given stage, saving the current orbit of the vessel, automatic staging, formulas for calculating transfers, the mass, parts, burntime, and switching between true, mean and ecc anomaly and a lot more.
For me it was just about testing what I could do, but in the end it's gotten bigger and bigger.
If anybody has improvements or tips for me how I can improve my coding skills your feedback will be deeply appreciated!!!
