Today's Progress: Learned about projections when it comes to REST resources in Spring. List of expenses now contains "real" values.
Things I've learned: How to access the system id without parsing the link / resource that is included. I'm using a projection to add the entity id as a property
systemId and use this in the list.
Things I've planned for tomorrow: Try to get the edit page working.
