+A helper for the Processing gifAnimation library (https://github.com/jordanorelli)
+ported to Processing 3 by 01010101 (https://github.com/01010101)
+Download the library from https://github.com/01010101/GifAnimation/archive/master.zip
+This helper was inspired by an example by Art Simon https://github.com/APCSPrinciples/AnimatedGIF/

+Put  at the start of your sketch:
+   add_library('gifAnimation')
+   from gif_exporter import gif_export
+and at the end of draw():
+    gif_export(GifMaker)
