## Additional coding style

### Extract inline type definitions 

For consistency and correct functionality of `core-tools` we need well-defined type assignments. 

Type assignments shall always be primitive types, classes, interfaces, enums or unions. Not allowed are inline type-definitions. Those shall be refactored accordingly:

```typescript
export interface SCPlaceWithoutReferences extends SCThing {
    ...
    // Use this:
    geo: SCGeoInformation;

    // Instead of:
    geo: {
        point: Point,
        polygon?: Polygon,
    };
}
```

### Reuse the map structure

If you come around a map-like-type use `SCMap<T>`.

```typescript
// Use this:
interface AnyClass{
    inventory: SCMap<number>;
}

// Instead of:
interface AnyClass{
    inventory?: Array<{ key: string, value: number }>;
}
// or instead of
interface AnyClass{
    inventory?: { [key: string]: number };
}
```
