Add a license file?

[mnestis]

Hi there,

Thanks for making your code available for independent review. However, reusing code without an explicit license can be problematic. If you're wanting people to reuse this code, it'd be very helpful to have a license file.

Thanks,
mnestis.

Hello, I am adding another request for this. We are hoping to re-use some of your code for a chatbot evaluation website we are launching. However, no license means you are giving people no permission to reuse your code (https://choosealicense.com/no-permission/)
Thank you,
Daphne Ippolito
