Tips on using restaf and restaflib in VA DDC

When running a DDC the app is running in a authenticated session. To enable restaf to use the current session, do the following:

async function setup() {
    let p = {
        authType: 'server',
        host: window.location.origin
    }
    let msg = await store.logon(p);
    ...more stuff..
}

All subsequent calls to restaf and restaflib will run under the current session.

An important point to remember is that restaf will handle the xsrf tokens for your applications - more cool housekeeping by restaf.
