Add solar eclipse, carousel and rocket examples

[leukipp]

All animations designed for 30fps.

• antarctic_solar_eclipse.csv
  • This is pretty much what the December 4 solar eclipse would have looked like on a sunny day (~100x speed).
  • It only makes sense to look on the x-z plane.
• carousel_gallopers.csv
  • Four colored carousel spinning clockwise.
  • Two gallopers spinning counter clockwise.
• rocket_launch.csv
  • Countdown followed by a rocket launch.
  • Experimental animation to test SVG to GIFT conversion.

Coded with GIFT-Development (#32), source code and running examples available here:

• antarctic_solar_eclipse.ipynb
• carousel_gallopers.ipynb
• rocket_launch.ipynb
