Complete community profile

[nalmadi]

EMTK doesn't have a community profile yet, so it is not clear how people can contribute to the open-source project. To help build a community around the tool, we need a few well written documents. You can contribute these documents by looking up tutorials and checking the repositories of popular open-source projects. The documents we need are:

1- Code of conduct
2- Contributing
3- License
4- Issue templates
5- Pull request template
