Fixing Multipage Error & Adding Completion Stamps (#43)

* Initial Fix

* Fixed multipage surveys

* update readme

* test csv

* Corrected numbering

The curr page is 1 forward.

* package-lock.json will cause install errors. Just keep package.json and then it will be auto generated

* Setting response insertion to have right type

* Adds completion stamp, queries supported in encrypted url

 Run `npm install` to install all dependencies. Run `npm test` to launch continuous Typescript compilation, watching for changes in any of the `ts` files. Leave this shell alone and, in a new one, run `npm start` to launch the application on the port in `.env`. With this setting it would start a server at [`localhost:4000`](http://localhost:4000).
