get_notification: Checking Notifications
In hmalmedal/ripplerestr: Ripple REST Client for R

This endpoint will grab the notification based on the specific transaction hash specified. Once called the notification object retrieved will provide information on the type of transaction and also the previous and next notifications will be shown as well. The previous_notification_url and next_notification_url can be used to walk up and down the notification queue. Once the next_notification_url is empty that means you have the most current notification, this applies for the previous_notification_url similarly when it's empty as it means you are holding the earliest notification available on the rippled you are connecting to.
