type Logger

type Logger interface {
	// Log a message at the given level with data key/value pairs. data may be nil.
	Log(context context.Context, level LogLevel, msg string, data map[string]interface{})
}

Logging interface, heavily inspired by github.com/jackc/pgx's logger. The primary difference is that `LogLevel` is a type alias rather than a newtype. This makes it easier for other libraries to support the interface (in theory), as they don't need to depend on this package directly.

Adapters are provided for pgx and log15.
