// MARK: - DefaultLogger

/**
The `DefaultLogger` is a basic implementation of the `CoreStoreLogger` protocol.

- The `log(...)` method calls `println(...)` to print the level, source file name, line number, function name, and the log message.
- The `handleError(...)` method calls `println(...)` to print the source file name, line number, function name, and the error message.
- The `assert(...)` method calls `assert(...)` on the arguments.
