Budibase Core backend library

This library contains core functionality, like auth and security features which are shared between backend services.

Note about top level JS files

For the purposes of being able to do say require("@budibase/backend-core/permissions") we need to specify the exports at the top-level of the module.

For these files they should be limited to a single require of the file that should be exported and then a single module.exports = ... to export the file in commonJS.
