Phoenix

This is a rebirth of the program, hence this name. Differences to the last release are huge

1. Instead of plotting in C++, in one program, we now have a simulator in C++ that simply computes and re-computes the simulation, and a visualizer in Python, that plots and re-plots the simulation. Both are triggered automatically when the input files are changed.
2. Much of the internal structure of the C++ code has changed. The most conserved part is the SPK file loading code, though even that has evolved a bit.

Thaumasia

• Time slider, allows quick jumps to arbitrary time points
• Experimenting with different color scheme
• Major refactor of internals

Phison

• Markers for simulation bodies
• Display layers: Key presses can now show/hide paths, markers and
  scaled models of bodies.
• More dense sampling. Not perfect, but better and without having to implement interpolation
• Code cleanups

Ophir

Notable features/changes

• New - more user friendly - syntax for scenario files
• Several basic spacecraft actions
• BodyTree allows keyboard navigation of bodies to use as camera center
• Text rendering! Shows the camera center and the state of the simulator
• Much more efficient copying of data, display no longer slows simulation or forces simulation sampling

(Trying out calendar versioning and named releases. Names will be taken from here (I sorted the list by increasing size of feature and picked according to how it sounds ) and are names of features of Mars. An important release will get the name of a moon, and a yearly release will get the name of a planet)

Chase demo

demo: Shows how to center camera on (chase) simulation object. Center object is hardcoded right now - this is just a technology demonstrator. The next version will be a rewrite of buffer and view to implement multi-level detail.
