LISA orbitography gif animation

Functions to build an animation of LISA space interferometer project path following Earth in the solar system.

For pedagogic / scientific diffusion purposes.

F5 in LISA_animation.m to run and create the animation file named 'LISA_orbitography.gif' that will appear in the same directory as you registered the .m file.

LISA spacecraft constellation draws an equilateral triangle, and each spacecraft path is shifted from its neighbors by 2/3 of a period (2*pi/3 = 4 months)

Old piece of code (updated for gif creation but not optimally factorized), but this is not the main thing here.

Please don't forget to rate this code if it helped you. Thanks ;-)
