Drawing Annotation on Storyline Slide

I recently started looking at this project again. I adapted the annotation example I posted earlier and added some test code for assessing the user-drawn input versus a couple of predetermined keys. This example used Resemble.js to compare the images. It has a numer of options that could be useful for finetuning comparisons.

The script is a hot mess right now and it is a bit slow due to a lot of extraneous debugging code, but it does a fair job at assigning a score to the user input. This example is contrived, but think of somethng like asking someone to draw in the missing path (in this case, the Arkansas River).

When I get a chance to clean this up, I will post a more complete example.
