Increase number of saved states for planetary encounters
- n is reduced if a significant part of the acceleration is not caused by the sun.
- CMake option: SaveRateOpt
SaveRateOpt refinement:
- only compile function when needed
- only run function during the saving period
Rename integrator for consistency, typo.
- RK67 > RK76 everywhere.
Merge branch 'md_RK76' into GSOC-Integrator
Print beta-corrected solar GM (useful for plotting semi-major axis),
other corrections.
Improve algorithm:
- Far less sensitive
- Fix possible integer division by zero bug
- Fix implementation in RK76
