What is userSession?

[majortom64]

In congito/cognito.js you have the following code:

export default class CognitoAuth {
// The constructor for this class will initialize our userSession
// as null
constructor () {
this.userSession = null
}

userSession is never referenced or touched again anywhere in the code. What does it do or why is it there? I cannot find any references to it in Vue.js, Vue Router or Vue, nor do I find a way it would be used by the Cognito JS SDK. What am I missing? :-)
