Can't find GifAnimation library.

Hi there.

When I determined that GIFs would be nice to generate I discovered the GifAnimation library. I downloaded the port of it for Processing v3 (discussed here: https://forum.processing.org/two/discussion/12737/gifanimation-for-processing-v3.)

I followed the instructions to put the GifAnimation folder in my processing libraries folder, but processing can't find it. ("The import gifAnimation cannot be resolve.") I believe it's in the right folder: Processing/libraries/GifAnimation. It finds other libraries there, but not this one.

Would appreciate any insights about how to get it working. Does it need to be registered somehow? I'm completely at a loss.

Thank you in advance for any help.
