Add basic SQLite implementation to track viewers created

[BeebBenjamin]

We need to add an SQLite implementation (it seems to be included in node.js: https://nodejs.org/api/sqlite.html) so that we can better manage user viewer creation. I would like to add the following API functions to facilitate this:

1. Create new viewer (including all the metadata needed)
2. Read and existing viewer or viewers
3. Update an existing viewer
4. Delete an existing viewer

We should have API routes for these functions and new methods called by them. I would like the new system to be as RESTful as possible: https://www.geeksforgeeks.org/node-js/rest-api-introduction/

Once this is in place, it paves the way for future improvements such as the ability to write persistent annotations into the static manifest.

I've started work on this!

Great! I was just about to start on this. Happy to help with any parts if useful.

I want to get my symlink reworking done, tested and merged first before I continue.

I have a WIP, I want collections generated by the docker or command line tools seamless in that all data generated can be curated by either the command line or webgui. I was wondering if we can get docker to create documents and folders using the permissions of the current user.

That means I will have to develop some methods in the command line tool to talk to SQLite too.
