## Refactoring Notes
- [ ] Create `Record` and `Note` struct types
- [X] Add `GKI` field to `Reading` struct type
- [ ] Encapsulate application data with an `AppContext` struct that holds a `Records` slice
- [ ] `LoadRecords`, `SaveRecords`, `AddReading`, `AddNote` receiver methods
- [ ] Standardize method names for getting user input to `handleNewNote` and `handleNewReading`
