-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)
