Topics colab now available

[Sam Dutton]

We've created a Topics colab*: colab.research.google.com/drive/1hIVoz8bRCTpllYvads51MV7YS3zi3prn

This makes it easier to load the tflite model that is shipped to Chrome for computing the topics provided by the Topics API. 

If you have feedback on the colab, please reply to this post.

*A colab (or colaboratory) is a data analysis tool that combines code, output, and descriptive text into one collaborative document. You can see a screenshot of the Topics colab here.
