### Logging
- Don't log directly to the console. Use our logging class `Logger` in "src/utils".
- Create one instance of `Logger` per file. Don't pass or share the instances.
- The first argument of the constructor is the scope. Use the name of the class or component whose behaviour you want to log or choose an explanatory name.
- If you want to add a sub scope (because e.g. you have two components that are similar or are used together, like the sub-classes of the iframe communicator), separate the main and sub scope with " > ".
- Scopes should be upper camel case.
- Log messages should never start with a lowercase letter.
- Log messages should never end with a colon or white space.
