DoodleNet Example possible inclusion

[shiffman]

In teaching about image classification, showing @yining1023's DoodleNet model complemented our discussion of MobileNet and Teachable Machine quite nicely. I made this simple example for my class. Perhaps we would like to include something like this in the documentation?

Phase I resolved by #196 .
Phase II is to add a learn page specifically talk about DoodleNet, and attach link to the learn page in light bulb tip.

@QuinnHe Thank you!! We will have a blog system soon on the Gatsby side. You can consider using the platform as well. Let's discuss the details soon.
