Provide example for eos-transit-anchorlink-provider

[Novusphere]

It's unclear without looking at code that you need to provide a "session id" to anchor's constructor when setting up the access context's wallet providers. Nor does anchor() throw any errors if you don't specify the session id. You just get an obscure error if you don't.

e.g.

        walletProviders: [
            anchor(`discussions`),
            scatter()
        ]

I am seeing

./node_modules/anchor-link/lib/link.js
Module parse failed: Unexpected token (100:12)

With

import anchorlink from 'eos-transit-anchorlink-provider';


const appName = 'My Dapp';

const walContext = initDefaultAccessContext({
	appName,
	network: {

	// walletProviders: [ scatter() ]
	walletProviders: [ 
		scatter(),

		anchorlink(Math.random().toString(36).substring(2, 15) + Math.random().toString(36).substring(2, 15)) 
	]
});
