[Draft] Separate Survey logic to separate package for reusability

[zabirauf]

Hey Tim,
Thanks for creating this. I like the way how you structured the Survey logic and made it easy to extend. I’m playing with React Native and wanted to consume the survey logic in it. Currently the repo is structured with both the web and survey part together. I was thinking of separating it out into two packages so that Survey can be published as NPM package independently.

I made the change to leverage Lerna for that. The PR is just a draft and still needs work to be able to merge. But I wanted to discuss this with you before making anymore changes to it. Let me know what you think or if you have an alternative approach in mind?

• Make travis work
• Update and move README
• Create README for Survey package
• Prettify according to the repo rules. (While changing it applied my local prettier settings)
• Remove .DS_Store files

*I might be missing something here :)

It would definitely help to separate all the Survey package stuff into a separate commit so I can review it easier. The difference in our linter settings is making it hard to see the actual changes.

@RISCfuture Updated the branch without my custom linting. Now you should be able to see the real diff.

Not sure why its not diffing correctly but the difference here is the new dependency on survey package

Thanks. I will need to check out the project and make sure it still deploys properly to the gh-pages branch for hosting, and tests still pass. Looks like the travis config also needs to be updated to run the separate test suites.

Finally, we'll need a better NPM package name than i-crashed-my-plane-survey. Maybe something like survey-tree (which doesn't seem to be taken).
