Include LICENSE

[lacabra]

Dear project maintainers,

First and foremost, thank you 🙏 for the amazing work that the ODK-X community has made over the years open sourcing the whole ODK-X Framework for the benefit of those that work on the front lines of resource constrained environment. Kudos to you 🙌

In order for many others to use the various components in this framework, they need to know under which terms they can do so, and that's where including a LICENSE in your repos is immensely helpful, as it can actually make all the difference in whether they can use or not depending on what license do you release this project under. I see that the documentation is released under a CC-BY-4.0 license, but I can't find any mention on the licensing of the actual code, and I can't find a LICENSE file in any of the individual repos, namely:

• odk-x/survey
• odk-x/tables
• odk-x/services
• odk-x/suitcase
• odk-x/app-designer

Should you need any guidance, refer to https://choosealicense.com/

As additional context, I am the technical lead for @unicef's Digital Public Goods Alliance with the mission to facilitate the discovery, development, use of, and investment in, openly licensed technologies, data models, and content of high relevance for attainment of the Sustainable Development Goals (SDGs). We have been compiling nominations for Digital Public Goods, and I would very much like to include ODK-X, but we need you to explicit a license to do so.

Thanks again 🙏
Victor
