Currently, when instantiating a logger by name instead of by object (such as when not in the scope of an object e.g. a top-level function), one has to use `namedLogger(name)`. This is not very discoverable – the user will simply get a "not found" error on `logger`, with no hints or IDE feedback on what to do or why `logger` cannot be found.
A better approach is to rename the `namedLogger` function to simply `logger`. When it is called within an Object without a parameter, the extension function will be used. When it is called with a parameter, whether inside or out, the named logger will be created. This is discoverable as the user's IDE will prompt for the missing `name` parameter when used from a top-level function, as in this scope only the named function is valid.
